Well I bit the bullet and went ahead with the new barrel install. Total length of new barrel is 11 1/4 inches from end to end. Still have about 1/8 of an inch before hitting the trigger guard when cocked. And NO the legacy barrel is not a direct fit. It measured .310 and the P17 barrel is like .273 at the smallest place, being the turned down part on the muzzle end that keeps the barrel from flopping around. After cutting my barrel to length and polishing the ends I had to drill out the hole for my barrel to go. No amount of twisting or hammering was gonna put a .310 barrel through a .273 hole I got it in and had to adjust slightly for a good fit at the loading end by the exhaust port o-ring. But it's in there and doesn't hit the trigger guard when fully cocked. Chrony readings coming soon.ThanksRay
This should explain it for you.I apologize for copying another posters picture and if that's not permitted please remove.THanksRay
BRCurious as to how you connected the stockBeen stocking this platform since 2016 (according to the notes) and feel that the plastic at the “heel” of the “lower” IS NOT thick enough or strong enough for a setup like you show in the pics. Also have to say I never tried it either..... SO I hope my assesment is wrong couple pics in the thread ( https://www.gatewaytoairguns.org/GTA/index.php?topic=166194.0 ) show my mounting. great to see others pushing the limit on these cool pistols!!
Not sure where you got the drawing, Ray,,, but that will certainly work. Drill/ream the muzzle to .398 to .400 or so and then secure the front of the barrel with a setscrew.D/T'd 8-32 and use two setscrews (one on top of the other) so they are locked...I've skinned this cat a few different ways but most of them started with a LW barrel for a 2300s. First thing is to part off the breech port:A couple different designs...And lastly, a modification to the lower frame...That provides the clearance for the longer barrel at the end of the intake stroke.All of the .177s barrels ended up at about 9.7" after the breech TP was removed. I did a .22 that was 11" (un-choked LW) that made nearly 4 fpe. Lots of fun..But agree with Clarky, the biggest gains are in the first couple inches...More (shameless plugs of) info here, and here:https://www.gatewaytoairguns.org/GTA/index.php?PHPSESSID=e954948fe94de2ab9cf24294ace04a00&topic=122164.0https://www.gatewaytoairguns.org/GTA/index.php?PHPSESSID=e954948fe94de2ab9cf24294ace04a00&topic=166452.0Wyo
