Well I work in an environment were I have a lot of people come in and give me there ammo, either through a firearms purchase or just looking to properly dispose of it. Well I went to the range with my Colt Commander Lightweight which has only had about 100rds through it, and proceeded to properly dispose of some ammo. I know your are already thinking STUPID! Ok I had that coming to me. My conclusion is that unless it is in a factory box, it gets destroyed! My 3rd round through the gun was a squib and the following round caused a lockup and failure to extract. Not having the appropriate tools to delicately examine my Colt without damaging the finish, I boxed her up and took her home. To my surprise the barrel had bulged about an 1 1/2" from the muzzle causing the lockup. Well first of all I am thankful that the Colt did not blow up in my hand. Other than the damage to the barrel, everything appears fine including the extractor. I am normally a Glock kinda guy, so I would like some advice on barrel selection and any other minor changes I should make to my Colt. Without spending a whole bunch of money, just looking for a dependable CCW carry piece.
