problems with my glock (placement

Does it extract and not pick up the next round or does it stovepipe or does it double feed or does it not extract or does the slide not even unlock or something else?

How much does your F1 can weigh? How long is your F1 can?

Hold it tighter.

The Gemtech Multimount is close to 2" shorter and 4oz lighter than your can. Maybe the unlock/relock timing is off?

I've not tried Hush 165gr, how does it fare with 147gr ammo?

You might be able to keep messing with the recoil spring until it becomes mostly reliable but then to keep from beating up your slide when you run it unsuppressed you'll forever be swapping springs and wondering if you remembered to put the right one in last time.

Other than measuring the spring and trying to figure out what it takes to compress it on your own I don't have spec's for the Gemtech booster spring. Maybe someone here will have it handy. If you can figure that out maybe Wolff will have something close.

You're claiming Failures to Extract as well as Failures to Eject. These are 2 different malfunctions.

Typical causes of Failure to Extract:
-Dirt and corrosion
-Damaged extractor
-Defective cartridge

Typical causes of Failure to Eject:
-Dirt and corrosion
-Limp wristing of pistol
-Defective ammunition
-Faulty ejection mechanism
-Spin back

Is your pistol clean and lubed?
Are you holding the pistol firmly?
Have you tried different ammunition?

For reference, my Octane45 is 12oz and functions perfectly on a stock G23.

... how to i measure the compression of it?

beyond my experience or skills, all I can do is google that one, theoretically you can calculate an approximate value

...
The spring is 1.243 long .843 wide ...

To accurately replace it you'll also need the diameter of the wire, coil count and material (assume some form of stainless) for starters.

Octane booster of course. It may act differently if you adapted it to a Gemtech booster.

You'd have to rig up a scale or known weight and measure how much force compresses the spring how far.

pounds per inch is the unit of spring force within a springs linear range. Force of compression divided by distance of compression is how you calculate it. Don't compress the spring all the way when measuring, that will take you out of the springs linear range.

free length : 1.243 long OD.843 ID .645 wire dia .099 6 coils coil space is 0.165 77.4 # per inch


does that sound right?

Maybe, I'd have to take mine apart to measure it.

Still out of my wheelhouse but with that data you should be able to find comparable springs. I'm assuming some kind of stainless, maybe 302.
