P series bolt O-rings?
This is my first post although I have been lurking for quite some time, I hope this isn't a really stupid question but here goes: I recently acquired a sheridan p-series (not sure which model but I think it would probably be a p68 or a LB based on pictures I have seen online) The gun does not leak and seems entirely functional except for 3 missing o-rings on the bolt. I measured the o ring grooves with a calliper and none of the common o-ring sizes seem to match I did find some that fit but they are too thick and cause the bolt to bind when it is inserted into the gun. Any help on which size o-ring I need and if possible a source to buy them would be greatly appreciated, thanks.
Pictures? They never hurt to have. I have been running mine on one thick o-ring, but it sounds like you have a speed demon bolt. I wouldn't imagine they would be different from a stock o-ring size
Try some 111s. If you want it really smooth, get some delrin ones from PPS.

Thanks for all the help! Not sure how to post pics here.... The diameter at the bottom of the groove is .505 and the bolt has a diameter of .682 the orings I found bring the OD of the bolt up to .695 so way too big to work. Is the 111 size a metric o-ring? The gun is also missing the trigger safety anyone have any ideas on where to find that?
111 (or -111) is a standard size. 7/16 ID X 5/8 OD X 3/32 W
You need the whole safety or just the ball and spring?

Thanks for the help I ended up getting some -111's out of an assortment pack from princess auto and they seem to work fine... the pump stroke is stiffer than I like but I think it will do just fine.
@MaD I need the entire safety assembly not just the ball and spring

I know this sounds obvious....but throw some lube on them before you put the bolt in too.

I did put a little oil on the o-rings but I think it needs a bit more... I was thinking something that was a bit more like grease would be better... any recommendations?
