My Springfield V10 Compact was reliable, I carried a 165grn +P Magtech and it shot them well. I changed the recoil spring when I got it (it was used) and never shot it enough to have any malfunctions before selling it. How is your Colt working out for you?
I carry my colt defender all the time.never had a problem with it I carry critical defence185 gr did shot spear gold dot 230gr but hard on the hands for a small gun. But was more accurate with the 230 gr.
I've carried a Colt Officers ACP and a Para-Ordnance Slim Hawg, which is a 3" 1911 like the Defender. Both are 100% reliable with Remington Golden Saber.
I have the lightweight officers model. Digests 200 grain LSWC Like crazy. Empties go everywhere. No problems except the white dots in the sights are long gone. I put CT Laser grips on it. 3.5" aluminum frame holds 6 + 1.
