1377 project

[MartinDWhite]

My favorite 1377 with the following mods

Grips by RBGrips
"2 stage" sear by big ed machine
Red tigger from custom shop gun
Brass front plug by me
dowel pin (instead of roll pin) pivot at front
Brass Flat Top piston by me
Valve modified by me
10.5 inch barrel
RJ Machine Long breech
Rear plug with mount by me (for in process add on shoulder stock)
Bottom of grip mount by me (for in process add on shoulder stock)
much stronger hammer spring
lighter valve spring
Reddot on top to work as pistol (long eye relief) or carbine (short eye relief)

10 pumps is 595-598
20 pumps is 709

That is a lot of changes to get it to shot what the box said when I bought it several years ago.

Agreed! They must test guns with balsa wood pellets. Nice job and excellent mod list.

What is the weight in grains of the pellets you are using ?
that will give us ftlbs of power your pistol is pumping out.

That pistol loves Beeman FTS.

The weight listed on Beemans site is 9.2, making it 7.31 ftlbs.
The weight listed on PA site is 8.7, making it 6.91 ftlbs.

It is about a 7 ftlb pistol at 10 pumps and about 10 ftlbs at 20 pumps.

Good numbers  thats a hard hitting pistol.
