Dont forget a 36 slide!

IMO this is one of the attractive aspects of the Glock line.

It's like big boy Lego blocks for shooters.

MDW Guns is now importing IGB barrels so you have more caliber and length options - including 7.5" long barrels:

The G30 has a pretty good kick with full-power .45ACP loads already. I think the G29 or a G30 conversion would probably be a real handful to shoot.

Lots of wrong answers. How about a right one? ;) KKM and a couple of other companies do make conversion barrels for the G30/G21 to 10mm; however, might I point out that the barrel hood is wider on a .45ACP than on a 10mm? Some report that those conversion barrels work 100%; others report that they experience extraction problems.

Some have done it with a measure of success. Rims on 10mm and .45 are different size so extraction/ejection issues may well arise...

I'd go with a conversion barrel. Better yet, buy the 30 and save up for the 29. :D

The only difference between a G29 barrel and a G30/10mm conversion barrel is the width of the barrel hood. Even with a conversion barrel, extraction appears to be hit-or-miss.

what about recoil? do you have get a xp spring?

I shoot a G29 and a G20. I'm running a 22# spring in the G20 and, I believe, a 21# spring in the G29. In my humble opinion, Glock 10mms are underspring. If you're throwing brass more than about 8', then you need a stronger recoil spring.

maybe i should replace the spring in my 30. i only got 250 rounds in it and it spits them way over 8 feet

I ran a 19# Wolff non-capture spring in my G30, before I traded it for the G29. The "8'" election max figure is from Wolff Springs' guidelines. Works for me.

I also run 19# Wolf springs/guide in my 29 and 20. Prefer them to factory.

Got the storm lake conversion barrel for my Gen 3 G30sf and here are my impressions. The Storm Lake barrel is well made and fit it pretty tight. The first round in the mag jammed 2 times but all extractions have been OK. Extractions are not thrown consistently though. You never know where they will go. The extractor just cant grab it tight enough to throw them like the 45 does. The chamber is very tight and there is very little unsupported case. It seems to do better the more I shoot it. At this point I would not carry it with 10mm for self defense but would in the woods. The loaded chamber indicator does not work in 10mm since the extractor is the indicator and the 10mm does not push it out like the 45 does. I have only shot one box of ammo so far so it is too soon to tell what it will do as more rounds go through it. I hear a lot about springs but the 30 and the 29 both use the same spring and I see no need to replace it. With 175 grain silver tips recoil is similar to 45+p and not punishing at all. Power wise I will say this, I have a steel tank that I have been shooting at and the 9mm, 40, 45 will not penetrate it, but they put nice dents in it. the 9mm+p will occasionally barely make it through but the silver tips make it through every time. The 10mm ST are suppose to be loaded to mid level at around 1200fps. I have no question this will handle max power loads with no problems at all and add a significant power boost over 45. With that being said, I love the 45. It shoots accurate and reliable and the 45 has plenty of power for SD. I carry it with 45+P 230 HS. However, most of the time I carry my G27 since it is pocketable and the 40 is more than enough for.

Cleaned up the chamber of the barrel and now its feeding as good a the stock barrel. No issues with ejection yet but decided to pull out the ejector and clean it up a bit. I filed the little tab on the ejector to allow it to go in a little further and now it ejects perfect. Picked up a wolff 21lb recoil spring to shoot full power 10mm but even with the new spring it throws 180 grain Remington brass 10ft and Win silver tips 20ft! No signs of battering and recoil seems about like 45+P. Very happy with the conversion so far. $140 for Barrel, $23 magazine, $40 wolf guide rod and spring.
