These are my Bullseye Guns, Top to Bottom, Colt Series 70 Gold Cup, Smith 52 wad cutter, center fire pistol, and a High Standard Victor 22 Cal.
I got the Gold Cup in the mid 70s, Good gun out of the box for center fire
45s, however, I shot on the AK NG Pistol team a few times (I was mainly a rifle shooter) and found with hardball loads the front sight would pop off. I replaced the front sight with a Millett Double Crimp type. I also replaced the prong bushing with a match type from Brownell's. I reamed the bushing to fit the barrel, but it still took more then a few hard ball ammo to get the bushing loose enough to function reliably. But once it set in, it shot like a house on fire. And still does, a heck of a lot better then I do. Remember I've shot this gun for 30 years. Once a year, depending on how much I shoot it, I use a gage and ping the rails to keep it tight. It'll shot light 185 SWCs with 3.8 grns of Bullseye, to full charge Hard Ball loads.
