Got this S&W M&P 40 pistol off a friend at a very reasonable price...because he has not been able to use it.

Problem is that any powerlet installed blows off all the Co2 before it even starts to get sealed.

I thought that I could solve it by soaking the seal overnight in pellgun oil - but no dice. :(

The tab seems to be cinching up the powerlet quickly enough - it just won't seal properly.

Am I missing something obvious - or am I just screwed.

Any suggestions? (IF I can't solve this issue; I will just sell it as is and let someone else try and fix it with full disclosure as to it's problem)

one old trick to try is putting a small bit of plumbers tape on top of the co2 neck. super cheap and it works alot. if it is leaking somewhere else your out of luck.

The plumbers tape is real thin.don't use anything else that will be to thick.

But it might still be worth fixing depending on what it new,

Worth s shot anyway. best of luck.

i don't know if its just the angle of the pic but the tip of that piercing pin looks a little buggered, and that end seal needs replacing as well. :wink:

Yup - the plumbers tape did NOTHING.

It is a piece of SH@T! :butthead:

If anyone wants it; you can have it for the cost of shipping it to you (about $15.00; I think). The mag works fine... :roll:

I gave a tutorial on this. If you're willing to venture out, here's a tip.
Two part urethane rubber is the cat's butt. Most hobby stores carry it. I use Alumilite Flex 80. Durometer is 80, very hard.
So, get your hands on this and do the following.
Using a dead cartridge, coat the end of it with a release agent. Mix up a small amount of Flex 80 (or whatever you end up with). Keep mixing slowly until the rubber starts to gel (setup), it will get a little harder to stir. Now apply a thin coat to the end of the cartridge, being careful not to get any into the hole. Make sure your coating is even and not running. Now gently insert the cartridge into the chassis. Do not apply pressure with the screw as this will displace the rubber. Keep the pistol inverted so that only the weight of the cartridge is applied to the seal. Now wait until the rubber fully cures.
The new rubber will act as a filler and create a new seal and it should adhere to the original seal if it is also urethane rubber. If the original seal is silicone, disregard this advice, it won't adhere. In this case, you would use a two part silicone product.

PS - I just noticed that you had added pellgun oil to the seal. You will need to clean this off before proceeding with this method.

Thanks for the info - but I have had quite enough of this pistol.

Someone else can take on the challenge of trying to fix it - or not; as they choose.

At least they can use your method if they want to try.

Cough cough. Have any of you considered, just remove the seal flip it over and use the gun :shock: :shock: . Most times it is due to over tightening, the seal takes shape of the powerlet neck. Take it out flip it around. If it doesnt seal. Contact manufacturer or build your own seal. JMO.

Thanks a lot for all the tips, guys - but it has been sent off to a good home.

The new owner has his own plans for it - good luck to him!

Most of the Umarex Co2 products can use a Crosman caplet seal (i.e. the $2.25 part that is $5.00 from a Umarex dealer (like us) for the "genuine" article, if they have stock. Piercing pin- same thing- $2.00 vs. $5.00.

These types of guns are labeled as "not fixable" not because they are not fixable- but no repair centre can charge little enough to make a $50.00 plastic gun worthwhile to repair-it's all "DIY".
