A #4x40 isn't quite right, and it's not metric (obviously) So what is the size of this screw? -J   Posted: Mon Oct 25, 2010 11:46 am 1377x Member Joined: 03 Mar 2010 Posts: 38 Location: upper midwest usa the screw is 4-48 there is a nice one here http://accustomparts.com/triggerspring.aspx or get another junk one from crosman but what i did with my stock breech screw was cut a slot in it with a dremel cutting wheel   Posted: Mon Oct 25, 2010 2:05 pm Slavia Moderator Joined: 31 Mar 2008 Posts: 4382 Location: Waseca, Minnesota, USA 4-48 is the correct size. If you're in the U.K. a 6BA will fit, but a little loose. A 3mX0.5 metric screw will fit, but a little tight: http://www.airgunhome.com/agforum/viewtopic.php?p=40168&highlight=3mm#40168 _________________ ¡Listo! ¡Apunte! ¡Fuego! 1377 breech screw     Air Gun Home Forum Index » Pistols You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum All times are GMT - 5 Hours   Page 1 of 1   All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First  Select a forum Main Forums----------------AirGunHome Q&AGeneral Air Gun Questions and TopicsPicture GalleryTarget Shooting: Casual, Fun and CompetitionHunting, Pest Control, Varminting People/Events/Airgun Issue Discussion----------------Introduce YourselfThe BS TopicClubs/Events/Regional/Political Airgun Issues Maintenance, Modification and Reviews----------------RiflesPistolsAntique, Collector and Novelty AirgunsBB GunsPellets/AmmoOpticsAccessoriesAirgun Smithing Buy, Sell or Trade Forums----------------For SaleWant to Buy   Note: If you are seeing "Please enter your username and password to log in."
