1300kt Info - Fat Pump Grip Make a difference - and Trajectory's?

[Marc]

I have a stock 1377 pistol, and I like it.  Really considering a custom shop with and 18" barrel 1300kt.

My questions are this - my pistol pumps pretty easy to pump #5, #6 gets harder, #8 is as far as I'd want to go regularly.  Do these pump easier with a fat fore grip and shoulder stock?

And is there any way I can find a trajectory difference between .177 and .22 cal., preferably from a 14.5" or 18" barrel?  Or any other ballistics to look at?

Thanks!

Marc, you described my 1300kt exactly. .22 with 18 inch crosman barrel with shoulder stock and long steel breech. The fat grip or old style backpacker grip is no longer available. You may be able to find one that somebody has put back from a rebuild or a no longer working pistol. The photo is my solution for a better grip to pump with.

How's accuracy with that barrel?  And trajectory?

I found some after market wood pump grips that I'd look at for sure.

 I added a rail and mounted a folding hand grip, keeps the fingers out of the  points and also extends the pump lever, for easy pumping.
