Merlin Orr Posted October 5, 2003 Share Posted October 5, 2003 Just started in Production Class with a stock LDA 9mm. I really like it but wonder if I would benefit from a different set of springs. I have reviewed the previous posts but have not seen anything regarding a 9mm. Anyone have any suggestions? Regards, Merlin Link to comment Share on other sites More sharing options...
Detlef Posted October 5, 2003 Share Posted October 5, 2003 different "set of spring"??? Do you have any idea how many (!) springs are in this gun??? Explain... I use a 10lb recoil spring, but an 8 lb works fine, too There appears to be not much benefit in changing the main/hammer spring from factory default. I tried and couldn't tell much difference. --Detlef Link to comment Share on other sites More sharing options...
Merlin Orr Posted October 5, 2003 Author Share Posted October 5, 2003 I was refering to the recoil and hammer springs. I know there are more springs in the gun than I care to replace...BUT, I stay out of the internals myself leaving that to my gunsmith buddy Dwayne, I am pretty much a total loss when it comes to repairing anything. What does the Para come from the factory set up with? Thanks again. Merlin Link to comment Share on other sites More sharing options...

That's what everybody else puts on their 9mm 1911's. Link to comment Share on other sites More sharing options...
Roger Sherman Posted October 14, 2004 Share Posted October 14, 2004 I have found a 9 lb recoil spring with a 15 lb hammer spring and an extended firing pin from Limcat or Dawson will produce a pretty good result without having to send the pistol to a gunsmith. The reduced hammer spring lightens the triggerpull, but it also reduces the force with which the hammer falls, possibly causing light primer hits. For a really good trigger pull, you will want to send it to a smith. My guy (Jim Anglin, Sailors Custom Pistols) in Omaha, has come up with some of the best LDA trigger pulls I've tried. Mine is well under 2.5lbs, with no overtravel. When I am trying to decide on a recoil spring, I look to see what my sights are doing, if the gun settles nose high, I use a heavier spring, the opposite also applies. I also make sure the spring doesn't bind (too many coils). I hope this isn't too much info. Cheers Link to comment Share on other sites More sharing options...
Detlef Posted October 14, 2004 Share Posted October 14, 2004 I have found a 9 lb recoil spring with a 15 lb hammer spring and an extended firing pin from Limcat or Dawson hmmmm...... you're fine with the spring swaps, but I don't think that an extended FP will still fall under the permitted modifications for USPSA Production Division under appendix 21.4 of the new rule book. Better check with Amidon before showing up for a big match... oh heck, I'm gonna write to him with that question. --Detlef Link to comment Share on other sites More sharing options...
Tom Freeman Posted October 14, 2004 Share Posted October 14, 2004 but I don't think that an extended FP will still fall under the permitted modifications for USPSA Production Division under appendix 21.4 of the new rule book. --Detlef Its a completely internal mod that helps ignite primers. I cant even begin to imagine that John would say its illegal, if its presented in the reliability aspect/manner. Welcome to the board Rager.

Detlef Posted October 14, 2004 Share Posted October 14, 2004 I'll let you know what he said. In IPSC PD, an extended FP is most certainly not permitted. But you are right, the reliability argument can be made for USPSA PD ... --Detlef Link to comment Share on other sites More sharing options...
Flexmoney Posted October 14, 2004 Share Posted October 14, 2004 IPSC and USPSA Production rules are completely different when it comes to trigger work. I don't see where an extended firing pin would be illegal in USPSA. In fact, 21.4 would seem to allow it? Link to comment Share on other sites More sharing options...
Eye Cutter Posted October 14, 2004 Share Posted October 14, 2004 I changed the hammer spring of my Para P18-9 LDA for IPSC Production Division to a Dawson 17lb and the recoil spring to 12 lbs. Measured trigger pull using an rcbs gauge is now 5.5lbs Link to comment Share on other sites More sharing options...

Detlef Posted October 15, 2004 Share Posted October 15, 2004 Here are our VP's words. I must worry too much... Now, how can we get John into revamping IPSC's Production Division? Hi Detlef,If replacing the firing pin is considered part of the action work, or enhances reliability, then as an internal modification, there is nothing wrong with it. We haven't gotten into tearing guns apart to view the internal parts, and hopefully, we never do. :-) John Link to comment Share on other sites More sharing options...

BE WARNED: Once you start the fiddling process, you'll usually end up with lots of sleepless nights either trying to make your gun work or deciding which of the little thingies work best or both.

Ken Kwiat Posted October 16, 2004 Share Posted October 16, 2004 MerlinD, I'm a firm believer in getting the gun to a point, through tweaking, smith-made mods, etc. that give you a reliable and competitive platform -- then resist the "never good enough" syndrome once you've met the first goal. In my somewhat limited experience with the LDA, this is one gun that you definitely need to get through that initial tuning process. I've shot them box stock and I've shot Roger's tweaked LDAs. There is no comparison. Especially when you're talking about such a long-travel DA trigger. As you are competing against Glocks (where folks have been able to achieve great triggers of late) and DA/SA guns like the CZ/Tan. variants, getting the platform to a competitve level will pay dividends, imho.

Borrowing quotes from a couple of our members. I believe it was John Dunn that said something about having a "bucketful of guns." Not only will one always be legal in some class but you will also always have one to shoot when you have just finished fixing another till it is broken. Ken Your words are very true.. However, The spirit is willing but the Tim Taylor just bubbles out of me. Link to comment Share on other sites More sharing options...
Ken Kwiat Posted October 16, 2004 Share Posted October 16, 2004 Merlin, I hear ya' brother. And I obsess over the shape of my mag release buttons on my guns. I've also spent more time than I care to admit polishing the outside of mag tubes! Of course, there's always Roger S. around to make my obsessions seem somewhat normal. Best of luck in your tweaking.

Tacblack Posted November 5, 2004 Share Posted November 5, 2004 In my single stack Nowlin super I shoot some idpa with I run a 12.5 ISMI and it works great for fast shooting returns to point of aim perfect. The load is a MG 124grn with 320VV @ 130PF Link to comment Share on other sites More sharing options...
