WHAT DOES BUY A GLOCK ONLINE MEAN?

I have a G22 that I bought for the obligation weapon about eleven yrs ago. I was going to purchase A further Glock in .357 right until I discovered I could just do a barrel swap on my G22. Concern is which brand barrel and where to buy it? I often CC it but mainly just shoot it at the range. Click on to grow..."You could train a person or lady damn
