need hotter loads to cycle the extra weight of the suppresser on the barrel. Try some IMI 158 and see what happens.

if you are going to run light loads subsonic you need a lighter recoil spring and all will be fine.

Mine did that with a new LWD barrel.
Lube the PISS out of the bottom lug and the lock up area around the ejection port. It took a few mags to free mine up with 147's. |

It's got a fairly new S3F barrel so I'll try lubing it real good and see if it gets better. Worst case I guess I'll look for a softer spring. No plans to reload 9mm just yet so I'll stuck running factory ammo. Thanks for the input guys.

I don't know anything about your suppressor. I have a Silencerco HD-9. Are you using a booster? From what I know, a Glock needs to use a booster to cycle a can. My HD-9 has cycled everything I've fed through it--including 147 grain Atlanta Arms subsonics with my gen 2 19.

The way it cycles though, you'd think I wasn't. |

Two things not helping.
The Gen4 recoil spring is too stiff (compared to a Gen3) Aftermarket barrels are usually a tighter fit and with the suppressor hanging off the end it causes issues until broke in...sometimes that takes 1000s of rounds. (unless you manually 'adjust' the fitting) My most reliable suppressed G19 is a Gen3 with a factory threaded barrel. |

I have an Osprey on my 19...runs fine ...The only time I ever had the problem you describe was when I put a big can (SWR HEMS II) on a small gun (G30) ..Hundreds of rounds and it never cycled once correctly ..I talked to SWR/Silencerco and they admitted there was a problem on the suppressor side but that it would work fine with a larger gun.They made good on it though and I eventually bought a G21. The HEMSII runs fin on that

It isn't the gun or the ammo. Sounds to me like the booster isn't powerful enough. I'd contact Surefire.
My gen 4 G17 runs just fine with a stock recoil spring and "bunny fart" 147 gr reloads as well as factory 115, 147, 158, and super underpowered American Eagle 124 gr Suppressor (subsonic 124 gr). You should not need a lighter spring to make it work with factory ammo. |
