A close friend pulled me aside and told me he got a 1377c. I figured I’d look around the net and see if I could learn a little about this Pistol. WOW this is perhaps the pistol with the most after market parts and upgrades going. I love that. I ran out and picked one up. After pumping it 10 time and shooting it once, I really do like it even though it’s multi pump . It’s light and despite it’s long barrel and pump handle it has a nice balanced feel. It is also very easy to pump, much easier than I remember as a kid. This pistol has a wonderfully thin body when sighting down the barrel. The latest design cocking handle / bolt assembly is very attractive and functional. It comes with an “adjustable” rear sight which amounts to loosening a screw on the top of the barrel and manually pivoting the whole sight assembly left and right for windage. This seems to have a slight affect on the elevation “adjustment” which again you loosen a small screw on th rear of the sight assembly and slide the blade up and down. The rear blade can be flipped 180 degrees to use the other end as a peep sight. It has a nice manual safety that’s easily disengaged. All in all a pleasant surprise with good power.
Now for the bad:
This thing has a horrid trigger but with a little work and a new #4 spring and nylon guide and a front spring to take out the slack. I slimmed the profile of the sear to reduce metal on metal contact and polished everything… it’s now decent.
The rear sight assembly cheap and crude. It is a pain to sight this pistol in and I have managed to partially strip the blade screw hole an easy upgrade though.
The pump handle makes a annoying clap, clap, clap as you pump it. I remember that from when I was a kid and I hate it!
If you don’t mind 10 pumps a shot, or perhaps 3 for indoor shooting,want an excellent price to power ratio, very good accuracy and available upgrades then this may be your pistol. All things considered, this makes for a winning combination as a beginners pistol or a starting platform for your own creation.
Fixes / Modifications:
* TRIGGER MOD 2: I found a picture on the web from an older Crosman pistol that had an adjustable trigger weight assembly. I pulled out my Hillbilly lathe (Drill in a vice)and drill press Dremel with a level strapped on it and was able to reproduce Using solid round aluminum stock, 4-40 threaded rod a knurled nut and a shorter spring and 3 set screws. Ask and I’ll take some Pix and email to requesters
* REAR SIGHT MOD:
the wood screw finally stripped out the hole in the plastic block. Again I used tiny threaded rod permanently affixed through the stripped hole put the sight blade back on and used a tiny knurled nut to loosen an tighten. (Both found on a Ink tip for a Staedtler Compass)I also filled the hollow of the rear sight with flat aluminum stock then Tapped a 4-40 set screw to keep the windage true if bumped.
FRONT SIGHT POST MOD:
I had some fiber-optic sight stock so I filed the front sight post with a mini round file to create a groove to cradle a piece of fiber-optic stock. I filed the end (facing the rear site) to a small rectangle. now it’s much easier to line up the sights.
PUMP CLAP, CLAP, CLAP MOD:
I reduced the annoying Clap, Clap, Clap of the pump handle by filling the handle with weather stripping and adding a thin rubber pad to the bottom of the chamber. Now extremely quiet.
I now shoot this pistol the most (I have 6 including a 10 meter competition) and really do enjoy it.
