It started life as a standard 9mm 75B, purchased at a local gun store in West Texas, maybe 10 years ago. I bought a Kadet conversion soon after, then a bunch of CGW trigger parts, converted the pistol to single action only. I started shooting bullseye matches with a Ruger but switched to the Kadet even for bullseye matches due to its 100% reliability, if it was clean. I added the rail to the top of slide and installed a Microdot sight and shot the pistol in bullseye matches for 5-6 years.
Over that time I put over 30k rounds through the pistol, so its current count is probably around 40k rounds, I've quit counting. It runs well even dirty, as long as the chamber isn't dry.
I was never happy with the factory 9mm slide as the front bushing fit was a little loose for a bullseye gun and the felt recoil was significantly higher than the P-09 I shot in bullseye matches until buying a proper CGW 97B"E". I eventually installed a CGW 10x bushing in the 9mm slide and the accuracy issues went away, so the original 75B was suitable for both rimfire with the Kadet slide and center fire with the 9mm slide. The 9mm slide assembly became my backup centerfire gun. I never needed a backup rimfire gun, but sometimes took the Ruger with me to matches in case someone else needed one.
I've only shot one timed fire 100-10x target in my life, and that was in practice with this pistol, exactly as shown in the photo. I've shot dozens of 100-nx rapid/timed fire targets with this pistol, however. My Ruger 22-45 remains s a safe queen and loaner/trainer pistol. The Kadet is the pistol I always take out when I'm rusty or injured or ill, and just need to shoot something well without a lot of drama or noise, LOL.
