I have had a 10 mm since the 80's, and love my delta's, but I also love the glocks too, the hi cap and they take such abuse, made them great side arms/back up when in Alaska over the yrs, not as pretty as a delta, but they work , hate to say it more reliable I think, dirt water weak handed, they seem to just work a little better,lLol
But will always have my colts!
