Thinking about trying their yellow spring or recoil mgmt system w/yellow spring in a Canik METE SFT Pro since it won't cycle reliably w/the can & stock spring

I used to buy them exclusively.

They are good quality, and I have yet to wear one out (but worn out a few cheap factory carbine springs).  I used to put a blue spring and H2 in all my builds, but eventually started having problems in some when they would get dirty or ammo had a different pressure curve.  Went back to using standard buffers and blue springs.  If I changed anything, I'd just go back to a white spring and standard buffer, and use adjustable gas blocks for badly overgassed barrels.

I once had a “standard” Sprinco spring render a rifle inoperable until I put the cheap DPMS stock one back in. Not sure what was going on but let’s just say I leave springs alone until something doesn’t work which is virtually never.  Will change buffers as needed.

how old is the pistol ? how many rounds fired ? What ammo are you using ?   A stock  spring or a replacement spring of the same weight and value should work fine with factory ammo that is not underpowered without a suppressor . Does it function well without the suppressor ? What brand of suppressor ? A lighter spring may help .
