WHAT DOES BUY A GLOCK ONLINE MEAN?

I've a G22 that I bought for a obligation weapon about 11 years back. I used to be going to obtain A further Glock in .357 till I learned I could just do a barrel swap on my G22. Concern is which brand name barrel and where to purchase it? I sometimes CC it but typically just shoot it for the variety. Click on to expand...Gen3 options provided chec
