I had to polish the feed ramp on my Colt Defender to make it reliably feed hollow point ammo. Great gun. 22.5 oz. unloaded, holds 7+1 rounds of .45 ACP, accepts Crimson Trace lasergrips. I use the Wilson Combat magazines. Accurate, reliable, small and light enough to be easy to carry, yet enough mass to it that shooting .454 ACP is no problem.
