They're both durable, accurate and reliable. You won't go wrong with either.
The two big differences are one holds 13 and the other holds 7 or 8 depending on the magazine. Of course the Glock is a lot thicker than the Sig.
Slim gun that holds 7/8 or fat gun that holds 13. That's pretty much it imho.

I know somebody will chime in about the difference in triggers.

Factory mags for the Glock 21 run about $20. For the SIG P220 they are about $35, but Novak's run about $23 and work well. I have average size hands and both are comfortable to shoot. The Glock 21 has the least recoil of any .45 I've ever owned or shot. It's also my favorite. The P220 is a keeper too.

Many people do have a loathing for the Glock trigger, but IMHO it does have a huge advantage over the SIG in trigger reset. Trigger reset is a very desirable quality for rapid shooting.

Blued 220s are more prone to rust than their stainless counterparts or Glocks.

My experience has been that accuarcy is a wash.

I have had both. I carried the SIG 220 every day for more than a year. It is a lot slimmer and easier to pack on your hip than the G-21. The grip is slimmer and easier to hold on to as well. The G-21 is so much larger that is not really in the same pistol class. I consider the SIG 220 to be a full sized pistol but the G-21 is an extra large.

As far as accuracy goes, I think it is going to be a wash depending on your luck. Some SIGs will shoot better than some G-21s and vice versa. Overall, they are very accurate and you should be happy in that dept. Reliabilty is probably a wash as well.

Trigger is better on the first shot with the G-21 but the SIG has the advantage after it goes SA.

Safety goes to SIG all the way! It is one of the safest pistols you can buy. The simple DA/SA with de-cock is much better than the striker fired G-21. The G-21 is basically a SA only pistol with no safety and no chance of a second strike in case of a weak hammer strike. This alone could save your life. The G-21s extra rounds could save your life as well however if you needed them.

I would go for the G-21 is you have hands like an ape and can control it. If you can pack it without a problem and can shoot it, why not carry some extra insurance in the form of a handful of fat .45s? For CCW, the G-21 is out of it's league unless you are 9 foot tall. The SIG actually conceals well.

The Glock is NOT a SA. :banghead:

FWIW my father with 22 years in the USMC and 4 of those being with Force Recon in Vietnam chose a glock 21 when he decided to do volunteer work for the police dept. He has put about 4000 rounds or so through it and beat the hell out of it, still runs fine. I'm sure a SIG would do the same.

Just a matter of personal preferance. See which one feels best.

G'day Tecolote, and et al.,

When I was shopping for a 45 acp both the G-21 and the P-220 were strong considerations for me. I must admit that I was slightly bias as I owned glocks in other calibers. I ended up getting the Glock as it met my needs better for fun shooting and carry during the outdoor treks about AZ.

I've found both to shoot well. Accuracy was roughly the same at 25 yds with the various ammo types that I've tried.

Where I found the discriminating factors were the following:

Standard Capacity of 13 + 1 goes to the Glock.

Size and weight, again went to the Glock in my case for ease of carry, even with a full load.

Trigger, this one is won by the SIG. The smooth trigger for the traditional DA/SA manipulation was impressive. A true joy to operate. The Glock trigger is just functional. (note: installing a Glock # 3.5 connector provides a lighter smoother trigger with less stacking at the end, nowhere near the smoothness of the SIG)

Appearance, this goes to the SIG for aesthetics as it does have a classic look. The Glock just looks like a Glock. I have had several friends who own SIGs complain about rust and corrosion. My Glocks have been out in the snow/rain with maintenance applied several days latter with no detrimental affects.

The biggest one was the ease of maintenance. The Glock was just much easier to maintain at both the standard field strip level and at the complete detail clean. This was rather significant to me as I tend to launch quite a few rounds down range on a monthly basis. Many of them are reload which can leave lots of residue.

I was fortunate to have access to armorer guides for both pistols. The Glock was just so easy to deal with compared to all the additional springs and pins of the SIG.

Please don't misunderstand, both pistols are fine examples of engineering and manufacturing. Both of them represent weapons that are completely suitable right out of the box for both casual and serious duty. In my selection criteria the Glock was my clear choice.

I've found that SIGs tend to instill an emotional disposition in their owners. Glocks are perceved as just functional tools. Best of luck in your decision and purchase! Both are good choices if you can afford both. Cheers!

If you are thinking about the G21 also try a G30. I had a similar decision to make recently and ended up with a G30 despite a prejudice against Glocks (due to a "kaboom" a while back with a G17). I have a couple G21 magazines for back ups.

You may also want to try the HKs for fun.

"The Glock is NOT a SA"

It soooooooooooo is!

For all intents it is a SA only pistol. Lets be honest here. It is not safe to carry unless you have holster that can hide the trigger. It has a short light trigger. I know it is a striker fired gun but that is not what the trigger feels like. I have a Kahr K-9 that is striker fired as well but it feel like a DAO pistol with the long smooth trigger. You would be more likely to "bump" the Glock trigger and have ND than the Kahr since the Kahr would take a longer pull.

The Glock firing mechanism might feel more like s.a. than some other designs, but it's certainly not s.a. A single action pistol, eg., XD, is cocked when the slide is retracted and released; Glock's only half-cocked.

I agree that I wouldn't carry a Glock in a holster that doesn't cover the trigger, but not because I'm under the illusion that my Glocks are s.a., as they aren't.

The Glock feels like a 4x4 post in the hand. The P220 grip is much better. You must have huge, gorilla-like hands to think the Glock 45s are comfortable to hold. No thank you!

With its accuracy and reliability, I doubt I'll need more than 8 rounds.

I love my P-220. It is the most reliable 45acp pistol I have ever encountered.

As one of the "gorillas" I found that a Hogue gripall (or whatever it is they call the grooved grip sleeve) helped with control on the shorter G30 grip, gorilla hands or no.

July 11, 2005, 03:32 PM
Both will work great I don't particulary like Glocks and do like Sigs. It is not emotional just a preference.

July 11, 2005, 03:36 PM
No comment, just thought I would add an illustration to the discussion.

The biggest one was the ease of maintenance. The Glock was just much easier to maintain at both the standard field strip level and at the complete detail clean.

I gotta call fooey on that, at least in terms of field stripping.

Field stripping a sig's a 4 step process that anyone can do forward and reverse blindfolded after their first couple of times:

-lock back the slide
-flip the slide release
-remove the slide
-shake the barrel and recoil spring out

IIRC, glock's got pretty much the same thing, except there's a mandatory trigger pull :what: in there somewhere.

For all practical non hair splitting purposes, they're equivalent.

As for detail stripping, I remain silent, not having torn any glocks down to components.

July 12, 2005, 01:41 PM
Sorry, but if you cannot figure out how to strip a Sig 220 or find it cumbersome in the least...thats really sad. Almost all decent semi-autos are pretty darned simple to take apart. Even a 1911 is not hard at all for anyone with half a brain.

Sure, the Glock iis a few seconds faster to take apart, but not enough to really be a stumbling block. You're splitting hairs, there.


July 12, 2005, 02:08 PM
Brickboy: Just curious as to how many rounds you've fired through your 220, and how many rounds through a G21 or any other Glock? FWIW, I know some 110# women that have no problem firing G30's and G21's. ;)

July 12, 2005, 03:06 PM
For CCW, the G-21 is out of it's league unless you are 9 foot tall.
I'm 5'8'', 160 lbs and carried one for about six months. It's no hot-weather gun, but it can be successfully carried by an average size person. Great gun, no malfs, low recoil. Sold only to fund another purchase. Sorry, no experience with SIG .45's.

SIG P220. The plastic thing and the sponge trigger just doesn't work for me. I like fine weapon craft. There is a reason why the SIG costs more.

good stuff, i know old thread, but i was looking for this info. God bless the search function.

June 25, 2007, 12:35 AM
Sig P220 hands down. I had to check this thread twice to see if it was real! :neener:
Glocks are good handguns, but the Sig is the champ between these two. The trigger on a P220 is second only to a nice 1911 IMNSHO. They are also well built and reliable. Also, there's no plastic guide rod or sights to replace :D
The DA/SA is my favorite of them. Sig without a question on this one.
Maybe YMMV, but....

Sigs are good shooters. They are expensive. They have a higher bore axis.

Glocks are good shooter. They are cheap. They have a lower bore axis.

Mama mia! This is torture! Get the Sig first since it is expensive and then buy a Glock.

June 25, 2007, 10:24 AM
It really all boils down to:

1. Do you like DA/SA trigger system or a consistent trigger?

2. 7-8 rounds in a magazine or 13 rounds? What is your preference?

3. Which fits you better? and are you willing to work with the gun?

Having owned multiple of both guns in the past, I have now pretty much chosen the G21 for my .45ACP needs. I really don't like the DA/SA trigger pull and much prefer a consistent trigger pull, I want the most rounds possible in a decent sized gun.

Even with my average sized man hands the Glock 21 fits fine, plus I am willing to work with the gun.

Pick the one YOU want and not what the rest of us tell you to buy.


June 25, 2007, 06:34 PM
I like both, I own both and I regularly shoot both. If you want a classic looking gun get the sig. If you don't want to fuss over wiping your firearms down get the glock.

I don't want to get into trigger pulls and all that, and reliability is also a wash. I've seen both guns fail (not mine of course) and I've seen both put through ridiculous tests and run like tops.

I will say that on average the sig will be more accurate. Your average shooter probably won't know the difference, but I've always been one to buy things better than my level as to improve.

Either way, both will serve you well. And you should probably pick up both at some point. One should fit your hand better since they are so different, so in the end I'd say get the one that "feels" right.
