Ok ,i like the simple stock look and all my mods have been mostly inside,the new metal breech has a red dot and i use a large quality UK made moderator which keeps the nuisance sound down.
But using a big moderator ,even with with the stock 7" barrel, its front heavy .
Now i think a heavy pistol is better for cutting down hand "shake" and im thinking of casting lead weights to fit in the recesses of the plastic grips. Ive made moulds/patterns and cast aluminium before at college and im thinking of using wax lost wax into plaster of paris then cast lead
anyone any thoughts of the idea of a heavier grip area or the practical side of casting
Yep this is what I did in 2009 http://www.crosman-air-pistol-owners-forum.com/board/index.php/topic,351.0.html (http://www.crosman-air-pistol-owners-forum.com/board/index.php/topic,351.0.html)
And another pistol I used sanitary kit to fill the grip cavities
I've used duct seal for more than just shooting at.

I've used it as a synthetic stock noise dampener also. Adds a good deal of weight also.
May check into it.
well Brutz..thought id ask you what " sanitary seal " is before i type it in my search engine......im sure the Missis checks my posts( she can kick off more than GCHQ on dodgy web searches i imagine )
Kit that seals showers and such
so after thinking about it it seems a good idea
im gonna look at mixing fishing split lead shot with epoxy resin and setting it into cling film "in situ",when its set i can simply pop it into the cavity...this might be a lot simpler than melting lead and casting.
I might do this in 2 parts per side of grip (one in the frame ,one in the grip) so its easy to fit
the question for Maths students might be what size of fishing split shot gives the maximum density per volume..ignoring the film of epoxy holding all the balls of lead together ?
il post pics if ever i get it sorted along with weights
I used a couple of tubes of 'Liquid Metal Filler' on a set of grips and that stuff worked pretty well.

Spheres of the same size will densify to about 2/3 of the "voidless" unit weight - meaning 1/3 of the total volume is air voids.

I used epoxy (slow setting and low modulus) with chilled lead shot #12
I painted the sides and bottom with the epoxy, poured in the shot, and then poured in the epoxy.
It really helped balance the gun :-*
thanks for the 2/3 rds rule...it would be a lot of work casting to get an extra 1/3 weight
im gonna try using lead fishing shot but setting it first into the hollow cavities in the stock grips to give them a better less cheap feel and enabling me to put on wood grips later if i change my mind
Done.
1 ,tested balance point of pistol which was just in front of the screw in front of the trigger{ balanced pistol on wooden dowelling)
2 decided i wanted new balance point on my finger when its on the trigger
3 tested small bags of lead shot taped on the grip till it balanced at my desired point
4 split this weight into 2 and mixed with a little epoxy to bind the small lead shot together and poured in insides of grip
5 pre checked that it wouldn't interfere with refitting and tested refitting as the epoxy went"green" so if it didn't fit i could remould it quickly-
6 after it had set tested balance again....perfect
the total weight of both my grips including the original grip plus epoxy and lead shot is now 275g,this suits my pistol as its fitted with a large UK moderator which ,whilst making it very quiet ,caused it to be nose heavy
also now the grips dont feel so hollow with a nice solid clunky ring to em when i tap em!
total cost about £4
well chuffed with it now ,feels like im not trying to stop it drooping and surly less shake
Sounds like you got it figured out. How about some pics? :-*

Yeas, nice job. And we love pics.
Ok a pic
not a very photogeneic pic,the thing was to steady my shaky hand and take the point of balance back to my trigger finger.
A and B mark before and after,i droppped of one grip but its only full of lead shot and epoxy sprayed up with black car paint.
luckily with the 2240 the usefull cavity is in the grips so if i ever want wood grips its no problem
If the pic of the moderator is a problem moderartor please tell and ill remove it,also am i allowed to talk about the moderator? its an over the counter UK bought item on a UK legal airpistol
if pic dont load ill sort it soon
cheers
pic at last
Looking good. :)
Well, they look like they came out alright. Especially if you got the balance point where you wanted it to be. :-*
Carl
Good mod sir.
Yes im very pleased with the results.If you use a 2250 balance might not be an issue as your other hand would naturally be on the front stock so counteracting any imbalance.But if your shooting a 2240 with both hands around the grips and with a longer barrel and sights/uv lights etc attached it might be an idea.
As ever I am guided by function deciding form
Hi mate great idea and one that I'm going to use once I have built my 2240 up, what mod is that? is it pretty quiet ie how does it compare to unmodded and where can I get one please? :-*
hiya mate
Its a swift "stumpy" designed and made by Richard Pope, a Birmingham gunsmith/precision engineer.
They are popular in the UK for HPA air rifles and FAC air rifles
Because of this they have recently been counterfeited so you should contact him to check approved suppliers and you can also pick one up from his workshop direct in person for £40,mine is multi chambered with separate screw on sections,its fine engineering from the city which invented engineering and makes a huge difference to the noise
ive not got a sound meter so i cant give any Db figures for reduction but its considerable

Your post is okay. We are an international forum so the rules are not too hard-lined regarding information like what you posted.

thanks Quickster
im up to speed with the politics of the USA situation as regards moderators, but i just was cautious because of the American members online and any grief i might cause them/you/this forum
thanks
Thanks UKairgunner!
