Hello, can anyone tell me what the factory main spring and recoil spring weights for a Para P18.9?
I'm trying out a few spring combinations out for competition. Recently I've tried a a 14lb recoil and what I think may be a 21 or 23lb main. With this setup the factory 115gr loads felt very soft and very light, almost 22lr like. The drawback is a very heavy trigger pull and a heavy slide return.
Then I tried a 10lb recoil and and 17lb mainspring. The trigger is very light, slide easy to rack but the recoil is pretty snappy and the slide action is a bit slower.
I've ordered a 12lb recoil and 19lb mainspring and hope to test it soon. I'm a novice USPSA competitor at my local club and trying to get a better tune for repeat shots and faster sight aquisition.
Any recommendations on other combinations? I've heard of people using lower spring rates as low as 7-9lb recoil springs and 15lb mainsprings, but because I usually use range reloads and factory ammo and don't reload, those specs might be a little too light.
Thanks in advance for your help.
