smk pp700w. pistol question.

[peddy]

Hello Peddy thank you for your interest. There is a loss of Co2 from the 'loading door' when the pistol is fired, I have an idea for stopping this but if I were to cock up the mod then a new door would be needed. Plan was to get a spare just in case! May be some other things as well, depends on availability.
I know its not exactly a major thing in the grand scheme of things but I just find it annoying.
Same with the .455 Webley and Schofield that blow. When you have only 2ft-lbs to play with every bit counts.
I do like to 'fiddle' with things, I really must learn to stop but at 77 years then what the heck.
Cheers.
Geoff.

I don't think you will find that its air thats leaking when you fire, mine does the same, I think you just need to make sure the 'door' is aligned properly. Any blast of air is probably coming from the movement of the hammer travelling. Have you chrono it to see if it is inconsistent?

Hello Peddy, in work I used to use a can of air Leak Detector, this stuff would pick up the most tiny of leaks giving a mass of bubbles. Max. pressure was about 120 lbs. so low pressure.
So I gave this one a squirt and it was like a major explosion in a bubble factory. I have heard, but not proved, that the 'O' rings as original are not of the best quality. As soon as I can I will order some English ones.
I will be back with what happens.
Cheers.
Geoff.

Guy at my club had the same problem, a wipe of silicone on the o ring did the trick.
T.Robb do a moderator adaptor for the pp700sa, not sure if it fits on the W.

Hi, well a change of 'O' rings and a smear of silicon grease has cut the AIR leak ( HA HA got it right this time, not CO2.) to an acceptable amount. A champfer on the leading edge of the door made for an easier life for the 'O' ring.
Thanks all.
Cheers.

Ive been hanging my nose over one of these. A few good reviews on youtube.

As anyone used one with a moderator, or could recommend one?

PP700sa has a cap you can unscrew from the muzzle and TR Robb do a screw-in moderator adaptor.

I use mine with a HW silencer and its extremely quiet, but quite long. rested on a bag we could hit the 45yd bell with it all day long. (scoped obviously, 30mm bell)

You can't fit one to the PP700w.
