    CHA-LEE's Tale

    Different hammers also have major effects to the actual unlocking process.

    Not all hammers have the same geometry as far as the force when closed and when cocked.

    Ed Brown, EGW etc all have different locations for the strut pin. This changes the fulcrum, add the FPS and hammer spring weight and there are many different results.

    USPSA's Value Proposition

    in USPSA/IPSC Shooting

    Posted

    I was the guy who ran the steel matches in Missouri for over 10 years.

    The issue I had at the time was there wasnt a classification system.

    So what drives the new shooters in USPSA is the classifier system, With no system at the time what was in it for our shooters, nothing !

    Also with steel challenge are the stages, shooting the same 8 stages are boring to most, we had at the time 32 different stages that provides variety and interest.

    Jim who runs the west coast steel is an old friend and they have mixed up the stages and its much better.

    Off center firing pin strike

    in 1911-style Pistols

    Posted

    Clark Custom used to make an offset firing pin bushing kit, It had 2 drills and a bushing with an offset hole to get the firing pin moved back to center.

    I have done a few with the kit and it worked well.

    I looked on there site but couldnt find the kit,

    They may still have them,

    Not for the faint of heart though, has to be done in a mill

    Cerakote Air Dry Application?

    in General Gunsmithing

    Posted

    The air dry is for High temp only, it cures with the heat of operation

    you have to beadblast with a very coarse grit and its a 1 pass coating.

    it doesnt like multi coats.

    the parts are small enough for almost any oven

    I do suppressors with the high temp and its a 5 day cure .

    The lower and upper need to be totally blasted and de greased.

    Keep the hardner ratio very low for a flat finish and high for a semi gloss.

    One shot at a time

    The trigger needs to just float in the frame , sometimes at the rear of the bow the metal frame will not have enough clearance and bind the bow, you may have to remove material at the rear top of the bow to clear the frame.

    There is a mandrel for the bow that makes sure the trigger face and the bow are square also

    How much WST for 9mm 115gr

    in 9mm/38 Caliber

    Posted

    Well I have used WST for over 15 years for 9mm

    4.5 with a 125lrn is a good load

    5.2 with MG 115 fmj is a sweet load

    the plated bullets are all junk in 9mm

    they are even softer than cast so usually are not very accurate

    I wouldnt have an issue shooting them as you loaded them

    but they prob wont be very accurate

    4.5 would prob work better but get some real bullets , either cast or jacketed , plated are not the way to go

    Tri-Glide Trigger Bow - Fits different in SV than STI

    in General Gunsmithing

    Who noticed the problem ???

    With little or no pretravel,the sear legs are already under tension. It does not take much moving mass for the trigger to bounce and trip the sear with minimal sear spring pressure required to get sub 2.5# triggers. More sear spring pressure can negate the doubling but trigger pull weight increases. Getting a reliable sub 2.5# trigger brings all factors into play. Trigger weight and pre travel being part of it.

    ++1 Yep, what he said. I first started working on the sear spring. Even with a lot of pressure on the left and middle leg, it kept doubling. Then I noticed the lack of pretravel. There was virtually none. Even with the tab on the front of the trigger flush, there still wasn't much pretravel. After getting rid of the ball bearing trigger bow, I started getting some travel and bingo, no doubles.
