Beretta Cougar hammer spring problems

[Bob the Angry Potato]

After my purchase of two matching Western Arms Beretta Cougars with Airsoft Innovations flow-restrictors installed, I had a quick question for any Cougar owner out there.

My slide doesn't always cycle- AI puts it as in warmer temperatures, the propane expands to the point where the hammer isn't strong enough to hit the valve properly. The suggested remedy is a stronger replacement hammer spring- this sounds about right, sometimes when the hammer hits the valve it makes a small 'pop' sound, and the slide moves back a few centimetres.

However, flow restrictors are meant for the .45/1911 family, not the Beretta- however, it works with the M8045 Cougar, luckily enough.

My question was this-

Is it possible to use a different sort of hammer spring in the gun- a stronger one, marginally- and if so, would WA M9 ones be compatible? I'm afraid I don't have a Western Arms M9 and none of the local players have them either to compare.

Any info would be great, links and such would be better.

As far as I can tell from this: http://tech.airsoftcanada.com/WA/WA%...AR-F-INOX2.jpg
It looks like it uses a method similar to the 1911 to retain the hammer spring. The only time I checked out a Cougar, I only looked at the slide portion, so I can't tell you if the hammer spring is anything close in size to a 1911 spring... However, what you can do is open up that spring housing and see if you can cram a BB in there, on top or below the hammer spring, and see if the hammer will still cock. Cheap man's upgrade hammer spring...

I'll try that, thanks.

Pictures and other such to follow.

Tried with a BB. It's too small, and the hammer refuses to cock when I use something wider.

I'm right now trying to widen the hole in a small nut from a broken tac-light to fit. Should marginally increase the tension.

However, after cleaning all the crap and corruption out and resetting the pieces, the action seems a LOT smoother.

Fixed.

Here's how to do it, for any other disgruntled Canadian Cougar owners with flow restrictors installed that are concerned with their weak hammer spring (all zero of them).

First, take a run-of-the-mill cheap ballpoint pen. I used some Bic I found in my room.

Then, dremel a small piece off it.

I really should've taken the picture when my gun was open, sorry.

Here's what remains of the piece I dremelled it from, and my Cougar.



After you do that, drop it in the top with that other metal piece. It works great as a spacer, though there's not much room- you have to get the measurement exactly right, or the hammer won't cock.

A complimentary stretch of the hammer spring won't hurt either.

After I put it back together, I gassed it up and put 10 rounds into a pile of laundry, cocking it back with my thumb- something I couldn't do before (it'd make a 'pop' sound and the slide would move back a centimetre or so).

If a mod could move this to Gas Gun Solutions, that'd be great.
