Form 1 Suppressor Cycling Question

[RSGentry]

Hi friends,

I recently completed my first Form 1 suppressor. It is 7.8" (including booster), has a titanium tube, titanium end cap, Gemtech LID, and aluminum internals. I don't have an accurate scale at the moment, but I think it is about .8 lbs.

The main host is my 9mm Walther PPQ M2 Navy SD, with factory threaded barrel.

In 100 rounds of regular range ammo (Blazer 115gr), I had about 10-15% failures to feed.

Of the failures to feed:

-0 failed to eject.

-1 slide hangup going forward, leaving the chamber open almost in "locked back" position but with a round ready. Slight pressure to the back of the slide sent it forward.

-In every other case, the cycle was very nearly completely, but just slightly out of battery and slight manual pressure to the slide completed the cycle.

Do you have any suggestions for improving the cycling reliability?

Thank you!

Do other silencers (if you have them) cycle fine on this host?

Did you lube the LID before shooting?

Heavier bullet

This is my first suppressor, and the booster was lubed.

Would a heavier or otherwise alternate recoil spring improve the forward motion without preventing the reward slide motion? Maybe a reduced recoil style recoil spring?

Thanks!

I don’t shoot a lot of suppressed handgun (other than 22LR). So I haven’t done a lot of trouble shooting with them.

But I read a lot about people swapping recoil springs to get the combination of host/can to function properly.

If all you shot was the one brand of 115gr, I’d also try a variety of other ammo options.

I gues I don;t even understand why you are shooting a borderline supersonic round instead of a 147gr subsonic.

Yes, thanks guys, I will try running with heavier ammo first and consider a recoil spring upgrade. I ran with the ammo I had on hand. I was going to pick up heavier subs from a supplier near me but they were out when I went it.

Weather includes a different spring in the box of their suppressor ready guns to use for proper cycling. Did you change that spring out?

Like it was mentioned I’d try a different ammunition (or two)

I’m sure someone around Wake has another pistol can and host they might let you use...different can on your pistol and your can on their host to see how it works

That’s my favorite factory ammo

If you want to run down to Statesville we can run some 147’s through it.

I also have another 9mm host and another pistol can. Send me a pm!
