SP-01 Recoil Spring Weight

[BeerBaron]

What you gamer guys think about 10# recoil for factory 115 ammo ??

too light. if running 115 gn that are shooting about 1150fps or so I'd be using a 12lb. but do some experimenting. springs are less than $10 each and take about 30 seconds to change.

Two CZ shadows, one has a 11 pound one has a 13 pound, the 13 pound seems to track the Sights a little better

Actually have this backwards, test it at the range yesterday, the 11 tracks the sights better, going to place a order for a 10 and experiment a little.

In all my semi auto handguns I run the heaviest recoil spring I can with the ammo I use and still get 100% reliablity.

For my SP-01 this means a 14lb recoil spring with a 13lb hammer with a 115gr load at 135 PF. For factory CZ mag springs I could see this causing malfunctions, but no problems for me with 10% mag springs or mecgar mag springs. CZ OEM mag springs are notoriously weak.

For my 40 TS this means a 16lb recoil spring with the factory hammer spring (20lbs ?) with a 165gr load at 175PF.

I probably have close to 40000 rounds or more in my CZ's and have yet to break a slide stop.

I tried the 11lb spring and couldnt tell a dimes worth of difference in the recoil impulse. Controlling recoil for me is more about my grip technique than anything else.

Agree with this ^^^

Shadows I run 13 and 13

TS I run 15 and 15

Haven't been shooting that long, but have 15,000 rounds in my Shadow and have tried the 11lb rec with 13lb main. Can't tell the difference

124 PD JHP N320 with 13lb shoots flat, quick tracking.
