Glock 40 S&W Barrel Conversions

9mm, 357 Sig, and 40 S&W

Having the diversity of calibers and barrel configurations for the AR-15 rifle makes it an excellent rifle that can be employed to take a variety of creatures. Similarly, some Glock pistols support different calibers, too. Glocks chambered in .40 S&W can reliably shoot both .357 Sig and 9mm ammunition. It's a great day when you have a gun that can shoot more than one caliber.

I can't start showing off pistols without bring out the 1911 platforms that have been around for a long time. Here is the full-sized Sig Sauer 1911 in stainless, followed by the shorter Kimber Tactical Pro II. Then at the bottom, that is a SA Micro Compact Loaded 1911A1. All are .45 ACP.

Glock Trigger Upgrades by Zev Technologies

One of the most routine of upgrades for any gun is a drop-in trigger. Since Glock pistols are so common it goes without saying that aftermarket upgrades would be available. Zev Technologies makes a great Fulcrum drop-in trigger for Glocks.  My recent trigger upgrades were in my Glock 19, 23 and 21. Each one was a little different because of caliber and since the fact that the 19 is a Gen4; the 23 is a Gen3; and the 21 is a short frame (SF).
