Excellent Barge! I had a Glock model 23 in .40 SW and it never failed to ftf, ever. Not much to them really, quite an ingenious design. My one buddy who was a Vietnam era veteran got it to stovepipe by limp wristing it, lol. He kept on me telling what a POS plastic gun it was...... 3 years later he bought it from me, lol.
I really dig my Rock Island. Big old thumper. ;-) Ballistics of the .45 ACP are on par with the old .45 LC loads. I went looking for another Glock for CCW, but after trying and checking out maybe 20 pistols, I fell back on the original John Browing design. He too was a genius and his design still stands after 100 years. I've been converted, lol.
