I have duputryn's syndrom in both hands now and I can barely grip a gun at all. I would trade in a blink. IMHO, you could easily correct for this (if it is the cause) by adjusting grip pressure or rotation on the grip to change finger position with respect to the trigger. Make sure your thumbs are off the gun and you are gripping only with fingers. Also, make sure the right trigger fingere base knuckle is off the gun. You could also try shooting left handed and see if groups improve.

+1 The reduced mass strikers increase strike energy by a large amount. I installed the one called "Lightning Strike" and showed a huge improvement. http://www.lspi.com/

WOW! What did they cut that with? It looks like that barrel was never crowned.

I assume any gun I buy will need trigger action work and I am ready to do it. But gross defects are another story.

That's funny.....

I think that there has been a very big (and intentional) change in business model. I think at one time, they cared about quality and had people who could spot defects. Around ten years ago, the advent of CNC machining made some people believe that you no longer NEEDED gunsmiths or competent people and they all got the boot. After all, make the parts precisely and you can hire min wage monkeys to throw them together. Ever notice that all the major gun makers implemented a "lifetime warranty" policy around the same time? It was supposed to communicate that the quality must be great, but in reality it meant that the "final test" was now being done by customers. Ship them all, the customers will return the defective ones and we'll try to fix them then..... after we have already cashed your check.

Nope. It's energy transfer which is 1/2 mass (velocity) squared. Increasing mass gives a linear return in energy, increasing velocity gives the return squared. Every "improved ignition" hammer, firing pin, or striker exploits reduced mass to increase strike energy. There was an extensive thread where somebody here developed a low mass hammer for SW revolvers that allowed reducing the hammer spring by about 70%. http://www.davidtubb.com/davidtubb/content/graphics/pdfs/DT_firing_pin_impact_studies.pdf After sear break (and still neglecting friction), the total kinetic energy KE imparted to the striker dur- ing its fall is: KE = (1/2)*m*V2 where m is the effective mass of the striker and V is the terminal velocity of the striker

I have not measured it, but it does not surprise me. There really is no advantage in making the tip longer, getting better striking occurs because the lower striker mass delivers more energy due to higher velocity. Changing the tip shape may improve it since it is trying to dimple the primer and not pierce it? The striker is going to stop forward motion when stopped by the round it hits.

The PC 627 I bought a few years back is the reason I no longer will ever buy another SW product. It's defects: 1) Barrel twisted (like yours) 2) Shipped with defective trigger lever (MIM part with no end, damaged rebound slide). 3) Frame not square, clearance between rear of cylinder and breech face was so narrow fired brass would sieze up the cylinder. 4) Barrel cylinder gap was "adjusted" by a gorilla with a mill file who chewed up the bottom side of the top strap. I had to do so much flipping gunsmithing on this thing just to get it to shoot. RIDICULOUS. Will never buy another new SW product again.

Couldn't believe how many points both defenses gave up. My dad used to say: "That's not a football game, it's a track meet!" The worst part was there weren't any close up shots of Mcarron's girlfriend preening for the camera.

So... lets set up places that stop traffic going in and out of the busiest airport on earth and see if we can back traffic up all the way to the Pacific ocean? What could go wrong with that plan....

I wonder what would happen if like 90% of the people going to the checkpoints told them tostuff it and turned around and drove the other way. The airport might suddenly panic because they realize the stupid searches are hurting their business to gouge people for air fares.

I think they would be equally effective... which is to say, neither would do much to reduce recoil. YMMV

Trojan. hand fitted by gunsmiths is better than mass made.

Not just legal.... it's standard operating procedure.

At the point where mayors of cities decided it was legal for cops to stop and search random people walking down the sidewalk without any probably cause. In case you didn't notice, the bill of rights got shredded right after 9/11 and it will take a while to get those rights back... if ever.

Then don't do it, but I shoot revos so I always make a habit of not putting my finger on the trigger until I want to shoot. It may be illegal in a given division, but it's no more "dangerous" than a revo. I just got sick of the light strike problem and screwing around with the gun. I haven't shot it in a while, I should put the stock parts back in and dump it. My point was that if the end of the striker is showing impact damage, it's hittiing the firing pin safety plunger and there are a number of reasons for that..... but the light strikes will probably not get resolved until they are fixed. "I'm pretty sure the striker was damaged by striking debris in the channel other than the plunger" I'm not sure what debris could get into the striker channel that's hard enough to put dents in a steel striker? Anyway, as an experiment, you could remove the plunger and see if the light striikes go away. If they do, you have the problem isolated. You can also ink the striker tip with a black sharpie and dry fire and look for contact areas.

The beat up tip end of the striker means it is banging into the firing pin safety blocking plunger as it fires. This reduces strike energy and creates light strikes. That plunger is raised by the bump on top of the trigger bar. Aftermarket disconnectors and trigger parts change the engle of the trigger bar and also the point where it releases the striker, which can lead to the striker firing before the firing pin plunger is fully raised. I went through this same thing on my G35, eventually ended up removing the plunger because it is such a PITA. But if you see impact damage on the tip of the striker, you can and probably will have light strikes because it is banging into the plunger.

I remember one time on a business trip to LA that the secretary booked my boss into LAX and me into John Wayne airport in LA.... which annoyed my boss because that meant we would each have to rent a car and he didn't want to pay the extra $50 for a car rental for one day. So he goes up to get my ticket changed so that we would both fly into LAX.... and after the ten minutes it took to do it all, the clerk said: "That will be $330." I had to fight really hard to keep from laughing. Spent $330 to save $50.

Found the thread about the improved magazines: turns out Rob Leatham designed them. http://www.brianenos.com/forums/index.php?showtopic=49147&hl=%2B9mm+%2Bsingle+%2Bstack+%2Bmagazine+%2Bleatham+%2Bdesign#entry562318 Here's the mag: http://www.brownells.com/magazines/handgun-magazines/magazines/springfield-magazines-for-1911-auto-prod20448.aspx?source=ir

I'm in the middle. I've put maybe 50k rounds through my 9mm Trojan, it's a great gun. Only "reliability" issues are magazine feeding as stated above. The first round nosedives once in a while. One of the top magazine makers made a mag for SS 9mm whose shell had a patented "feed ramp" formed at the front of the shell to prevent nosedives? I remember thinking that was a smart idea.

The new disconnector changes the point at which the striker tab releases from the trigger bar. The disconnector can also alter the height of the trigger bar which influences it's position with respect to the firing pin blocking plunger. Your light strikes are from one of two causes: 1) The striker releases farther forward (less striker spring deflection) and it no longer has enough energy for 100% ignition. 2) The striker is releasing with the trigger bar at a position where the firing pin safety plunger is not fully raised and the striker is bumping into it coming forward. The Glock trigger system is easy to screw up with aftermarket parts. EDIT TO ADD: a reduced mass striker does increase strike energy and will typically resolve a "marginal strike" condition. A stronger striker spring will too, at the cost of heavier trigger pull. And softer primers obviously would help as well.

IMHO, what feed problems the 9mm 1911 has is due to the 9mm tapered case which tends to nosedive into the feed ramp. I believe the 9mm feeds a lot better if "loaded long" and fed through .38S magazines. I use .38S magazines with standard 9mm rounds and it feeds about 99%. Once in a while I will get a nosedive on the first round coming out of a full magazine. When I only load nine rounds into the ten round mags, feeding is basically 100%.

I also notice the Wolf spring kits always include an increased power firing pin spring. I wonder if that is lawyer proofing because a stronger FP spring makes the gun less likely to fire on a muzzle drop or on a slam fire. But a stronger FP spring also makes light strike misfires a problem if using a reduced power hammer spring to get a lighter trigger pull. The only time I ever saw any use for an XP firing pin spring was in cases where the primers showed "primer wipe" where the case was being extracted before the firing pin had retracted fully. That is a very rare occurrance.
