"Bought this for my Nov. SSP1

The bottom cap needs to be filed- the lip that comes up the front of the mag doesn't allow the mag to click into the pistol. Had to file it down to make it work- easy enough. Not going to ding the mag for that.

Not much else to say- works as intended. I only get 1 mag out of 1 Co2 cartridge.

I only use my side arm 2-3 times in a full day, so atleast I'm getting all of my Co2 by the end of the day instead of having to decompress the cartridge and waste air because I didn't use it enough.

"No where does it tell you how long to fill it, I placed mine under gas for 7 seconds and got off a magazine and half. Mine wasn't even full still. No idea how long you can fill it, I believe 8-10 seconds max??

I filled mine up in 86F weather, lasted all day till some CQB action. I put two drops of oil in my propane tank and 2 more on my o-ring seal. I always shake the magazine after filling maybe that helped hold more gas? I heard to shake your magazines anyways. I also have the silver colored WE ones, those are nice too. 5/5 star both products.
