501 in 22lr. My 501 got banned from the local 22 rifle sillywet matches,

Had to chuckle myself.
30-40 years ago the center fire bench rest guys started building some really nice bench rest pistols and some of the top shooters were getting on board. Didn't take long for the rules comity to ban them.

By the time I purchased my first striker I had 4 xp's. For hard pounding field use I prefer the striker in its factory stock. You could drop it on the ground run it over and it won't hurt it.
