Trigger slap on a Glock 27 and POI

Glock - Trigger slap on a Glock 27

Just recently picked up a Glock 27 and I really want to like it.
The size is nice for carry, but I am not very accurate with it.
Is this because it is a Glock, because it is a .40, or is it me?

Also, and my main reason for the post, the trigger slap on this little guy seems to make it a little uncomfortable after about 50 -75 rds. or so due to the fact that the pad of my finger starts to go numb, does anyone else have this problem?

It is a 3rd gen. Glock with finger grooves, I have read here that that the finger grooves may be a part of the problem but in all honesty I do not plan to trade my new G27 for an older 2nd gen. Or could this problem be due in part to the serrated trigger....

This is my first Glock, I have been a Sig and Beretta man so I don't know how much of this is a problem or if it is just what to expect with a subcompact Glock.

I want to keep it due to the size and caliber, and I have already improved greatly with a bit of practice, just asking for a nudge in the right direction and seeing if anyone else has been down this path....

Glock triggers are a little different and take some practice to be able to use. There are a few different things you could do if you want to.

Glocks are pretty modular, most models share parts, this makes them home gunsmith friendly. Good disassembly instructions are easy to find. glockmeister.com is a good place to look at, that is where I learned to detail strip glocks and swap out parts.

Some options:

1: Your serrated trigger can be swapped out for the trigger set from a G17 which is smooth. I swapped my trigger on a G30 for a G21 trigger and I think it is worth the effort.

2: Your 5.5 lb connector can be swapped out for a 3.5 connector which is the factory part for the G34. You may or may not wish to do this as it will lighten trigger pull somewhat which could be dangerous, but it's an option.

You can also search around for instructions on where to polish the trigger parts for a smoother pull. I like to disassemble the trigger group now and then and lube it with grease. I think it smoothes things out a little and last longer than oil.

The glock armorer at a GSSF match swapped the trigger on my G30 for free (even the part), other glock armorers may do this too I don't know. Search the parts classifieds here and on glocktalk. There is a guy that sells the 3.5 lb connectors for cheaper than I could find elsewhere and can sell you any other factory part for a good price.

I believe the trigger slap is caused by the striker re-engaging the sear when the slide goes forward. I started noticing it a lot more on my G23 after installing an increased power striker spring.

If it's really uncomfortable, one option may be to get a reduced power striker spring for practice. It's a real pain to swap striker springs, though, so you may want to buy a second striker and the various other parts, and just swap the entire striker unit. Cost would be about $40 - 50, I think.

Let's see. On http://www.lonewolfdist.com
firing pin - $35
spacer sleeve - $2.50
spring cups - $2.50
reduced power spring - $4

Seeing how this is a new 27, is this something that will go away in time, kinda like a break in period? I have no clue, just thought I would ask.....if not, $40 seems like a good investment!

You won't need a new firing pin (striker?). Changing the firing pin spring is quick and easy, and you can get a new spring for a couple of bucks. I'd start, though, by trying the smooth trigger from the G17/22. If you install a lighter firing pin spring, you'll risk light strikes.

Easy? I've sent those darn spring clips rocketing across the room a couple times when trying to compare trigger pulls. If I did that at the range I'd never find them, and I'd be left with a rather inefficient club until I ordered some new ones. Such as it was, it took about a half hour on hands and knees to find them again.

If I were swapping springs to eliminate trigger slap, I wouldn't want to change the springs at home, and be left with a potentially unreliable gun on the way to and from the range, so swapping at the range it would have to be. A lot of people have absolutely no problem with a reduced power striker spring, but I prefer not to take chances. Getting a second firing pin unit would eliminate all chances of fumbling and losing tiny little parts.

Oh, another thing you can do is file down the trigger safety a bit, so that it sits flush with the trigger face when fully depressed. I think the trigger safety pokes your finger a lot more than the serrations do. Doing so may eliminate the need for fiddling with the spring.

And because of the way (that I think) trigger slap is caused, an eventual lack of slap would probably indicate that the firing pin spring is getting worn out.

Trigger slap? I've never experienced any such thing on a Glock. Have you ever experienced true trigger slap, like from a crappy AK?

You're probably just getting sore from the serrated trigger and trigger safety combined with the snappy recoil of the .40sw in a lightweight handgun. Try getting a smooth trigger and sanding down the safety so it's flush when depressed.

All subcompacts have finger grooves on the grip, even the "2nd generation" ones.

Middy and all,

Thank you for the help and the correction about the 2nd gen. s/c.
BTW, never had to endure a crappy AK-47, sounds like I am lucky in that regard.

The only Glock I've ever shot was a G27, and it was one of the most accurate pistols I've used. It was with the owner's pet handloads, but it was very accurate. No problem with the trigger for me. I only fired about 25 rounds with it though.

Are you following through and keeping the trigger pressed to the rear after the shot breaks?

 

[Rockstar]

Let me rephrase: Changing the firing pin spring SHOULD be simple. I can't vouch that it'd be simple for every human being on earth who might attempt it.

Per another post, I've fired a lot of rounds through Glocks, and I don't believe that the phenomenon of trigger slap exists in Glocks. Whatever's going on with that G27, it's not trigger slap. I use smooth triggers on my compact and sub-compact Glocks. Sometimes, I've found it necessary to slightly contour the trigger safety on a Glock's trigger. (Such contouring SHOULD be easy, but I can't vouch that it'd be easy for every human being on earth who might attempt it.)

Thanks for the replies, I think ya'll are onto something with replacing the trigger to a smooth trigger. I dry fired my 27 about 40 times or so this weekend and I started to feel the same thing in my finger, so it's the serrations.
Any recommendations on where to pick up a smooth trigger.....

Thanks again...
