While cleaning my Umarex Smith and Wesson M and P 40 .177 BB air pistol, like a twit I got the eyelet jag and small piece of Bisley cotton cleaning cloth oiled with Pellgunoil jammed.
When I eventually pulled it out, the inner barrel remained stuck outside the pistol barrel. Can anyone tell me if this Pistol is still safe to be fired, or does it need to be repaired of have I just kissed goodbye to the £50 I spent on it a couple of weeks ago?
My fault entirely of course, being too green, too keen and trying too hard!

Okay, so I have sorted this one out myself and rightly or wrongly this is how:
1) Hold onto your hat! … I tried to gently knock it back in with a ball-peen hammer … nope, that didn’t work.

2) I tried dry firing it (no CO2) … that didn’t work

3) While pointing the muzzle sky ward, I put a drop of Pellgunoil on the outside of the inner metal
barrel that was sticking out and swirled it around so that it would track down between the inner metal and outer polymer barrel. I tried tapping it again with the hammer but still no joy.

4) Then I tried adding Pellgunoil to the front and back of the trigger mechanism, (well the parts I could see and gain access to), wiping away the excess. Slowly and gently I worked in the oil by pushing and pulling the trigger, gradually increasing the range of movement and hey-presto, the inner metal muzzle started to move ever so slightly.

I added a little more oil between the 2 barrels (taking care not to get any inside the metal one) and a little more oil around the trigger, more gentle working of the trigger and eventually the inner metal barrel popped back into place.

I then tried a dry fire and the gun worked, so I dry fired a few more times and yes, the action was a little stiff and sticky at first, but improved when a little more oil was applied to the outside of the inner barrel as it protruded and after several more dry fires the gun seemed to be working fine.

I left the gun on some kitchen towel (to catch any oil that might seep out) with the muzzle pointing up. I left it for about an hour and then did a few dry fires and repeated this over the next few hours.

Then it came time for me to test the gun out properly … so, new CO2 and magazine loaded and I’m armed with a safety glasses and stainless steel wire safety gloves on and with a good bit of trepidation and quite a few shakes (did I say I am new at this air gun business?!) … I fired the gun and voila! … the gun’s a peach and still accurate, I just saved £50 quid and I’m well chuffed!

Okey-dokey, as I say, this was my method and I am certainly not recommending it for anyone else to use, but I am simply letting you know that thinking around a problem can sometimes work, while you are waiting for someone else to come up with the answers for you!
