I give this pistol high marks. I am a fan of the 1911 45 ACP, and yet am always looking for a light conceal carry weapon in a minimum of 40 cal. This fits the bill. I have found the gun to be reliable and I can shoot it well. Keep looking for one lighter! I've not had jamming problems. I think many problems with well designed autos jamming is the ammo. - J. M.
