I have my OD framed glock 29 on my hip right now. I decided I liked it enough to buy a holster and reloading stuff this past week.
I picked the gun up in a trade and I think I scored. It came with TWO 106mm barrels. One in 10mm and one in .40 S&W. The mags function flawlessly with .40 so far too. Just have to aim a bit higher.
I only put two boxes of .40 through the gun though. It just doesnt feel good to go from the recoil, blast, and flash of 10mm to the pop of .40
I dont want to be shot with either, but now that I have a good supply of ammo, and all the extras, I am sticking with 10mm.
