My 1377's, Got flat top on both, from AC and Mellon. Got Power adjuster on the carbine in case I want to go over 10 pumps. I mostly go by 10 which gives me 726fps with cpl 7.9. If I go 15 pumps I get 2 low shots for it does not dump all air, got it back down for 10-12 pumps which is plenty to 20 yds. Didn't want to go full time strong spring for I have the heavy hit of the hammer even on low pumps. Power adjuster can take care of the variable pumping. Pistol shots 662 with 10 pumps with cpl. These are my go to nutter buster that loves digging around my backyard. If you don't get crazy on the mods..metal breech, flat top, solid pivot pins, LDC and 18 inch barrel...with base 1377 pistol you can easily add $150+.
Here are 2 ways to go with a 1377 carbine. Uploaded at Snapagogo.comUpper: Hunter - 24” barrel with reflex shoud, 3-9x40 UTG scope, standard 1377 tube, wide forearm. 705 fps at 10 pumps (8.4 g JSB Exacts)Lower: 10m freehand target - 19” Lothar Walther match barrel, power master 66 tube, reduced volume valve, highly adjustable rear stock, custom pump arm, free floating barrel, breach strap, Avanti aperture sights. 465 fps at 3 pumps , 525 at 4 pumps (7.0 g RWS Hobby)Common to both: steel breach, hammer preload adjuster, flat top piston/ ported valve, 1701p trigger, 1399 rear stock with 3rd screw mod, extended probe bolt, stainless steel safety, Kydex cheekrest, match trigger shoe. I made the vast majority of the custom parts, but you still don’t want to know the cost...JMJ

Brandon we had that same law here in Michigan about the .22 air pistols, heck I bought a .22 38T Crosman pistol back when they first came out and never really used it after that law went into effect. Only a few years ago they finally lifted that law and pretty much it's the sky is the limit here when it comes to airguns, we can even hunt big game with them now. Our law was any air pistol with rifling .177 and up had to be registered according to the way the law was, also black powder pistols were the same way but that's finally gone now too. I hope they get it together there in Illinois.
Quote from: JimQwerty123 on November 21, 2017, 11:12:34 PMBrandon,I converted a 1377 to a carbine a couple of years ago but I didn't keep track of the cost. I added a metal breach, 18" Crosman barrel, new barrel band, and a shoulder stock. It's accurate and easy to pump. I don't have a crony so I can't give you FPE but I have taken pest birds out to about 15 yards with head shots. I have not tried longer shots at pests. Accuracy out to 25 yards is good, for me in the 3/4" range (that's good with my eyes). I also added a TKO LDC. If I had it to do over again I would go with Crosman Custom Shop 1300KT. Last year CCS had a great Black Friday sale. JimI believe last Christmas I got my 1300KT with camo stock and 18” barrel for less than $100...using code and free ship Friday...I think I ordered 3 guns in all

It's VERY quiet with the TKO.
Do you find that the TKO improved the accuracy any as well? I've read that sometimes the LDCs do because they "peel" away the puff of air as the pellet exits the barrel so there's less turbulence around it to kick it around and skew its direction randomly at the beginning of its travel. I think they're ugly, so I wouldn't add one for the appearance; but if it will reduce the noise and/or increase the accuracy, it's definitely worth it.
Guess who finally ordered a 1377. Yup this guy did. Going to have some modding fun
