Glock 21 and SilencerCo Osprey

[rn29306]

I have a G21 45 ACP, SilencerCo barrel, and Osprey 45 suppressor. The slide will fail to return completely forward after a shot quite frequently. This appears to be a frequent problem. Some people suggest a stronger spring and some say it’s a fitment issue. This was shooting ball ammunition. 

I did take the pistol to the Outpost Armory yesterday after being told they would take a look at it. Today i received a phone call to come and get the gun. The gentleman stated there was nothing they could do to the gun and Glock wouldn’t look at it due to it not being a stock barrel. I never asked them to send it back to Glock. They have performed gunsmithing in the past. They sell these components but cannot or refuse to attempt to diagnose a problem. I don’t understand this but I look forward to speaking to their manager when I pick up my items. 

Thanks for any help you can provide as to how to go about getting this issue fixed.

Does it fail to return without the suppressor?

I went through this with my G19 and Osprey 45 when I brought the Osprey home. I know this doesn't help but the problem fixed its self. Other than some lithium grease on the piston I haven't changed anything. Best of luck to you.

It shoots fine with the stock and threaded barrel without the suppressor.

Thank you. I will get to greasing the piston. How many boxes of ammunition do you think it took for yours to correct itself? 

I really appreciate your post.
