Recoil spring replacements for FM Detective 4"
I'm looking for replacement recoil springs for the FM Detective 4" models. IIRC the 1K rd mark was the recommended replacement time frame (like 1911s). I know mine has close to that through it, and I'd like to get it changed out before something starts peening. I remember a few threads here over the years, and Archive search revealed little.
I recall one of the guys from Argentina had contact information for someone who worked for/with FM, and might be able to source factory springs, but I can't seem to find the info now. There were some folks that had luck with Cz75 springs if memory serves, but I'd like to get some (captive / double spring) factory replacements if possible.
Hi, I just today noticed the answer to your question. FM Detective Hi Power Recoil Springs: Fortunately, Wolff CZ-75c 18-pound recoil springs work well.
Wolff CZ-75 Springs are the same kind as used by EAA Witness firearms. If you look here (http://gunsprings.com/SemiAuto/CZNF.html#CZ7588), it directs you to the EAA section of the website. You want the EAA Compact (http://gunsprings.com/SemiAuto/EAANF.html#RecoilCompact) springs at 18 pounds, or part number 43318, "CZ, TZ, P9 and all other Compact models." Wolff's website is pretty confusing when it comes to these springs.
I am planning to buy a Detective. FM High Power guns are well done. Rr
While the Wolf spring would likely work but typically seem to be very long, you may find a better answer by contacting a couple of the better known Hi-Power custom gun smiths. Sure they would steer you into the correct or better path. If I was going to buy a Wolf spring I'd likely first look at the FN/Browning stock replacements. So no luck contacting FM in Argentina?
