Throckmorton,23149 Posted April 3, 2019 Share Posted April 3, 2019 been learning myself about the inner workings of my yellwboy, and got to wondering ab out it. does it make it fire more reliably with soft primers, or imaybe it's just replacing a part before it's a problem?? ie : it breaks. ? thanks, Pards Link to comment Share on other sites More sharing options...
The Original Lumpy Gritz Posted April 3, 2019 Share Posted April 3, 2019 With Marlin 94's, it's a known design flaw in the front part that breaks. OLG Link to comment Share on other sites More sharing options...
Caboose Posted April 4, 2019 Share Posted April 4, 2019 Takes less energy to fire the primer with a one piece resulting in lighter main springs. Link to comment Share on other sites More sharing options...
Cactus Mike Posted April 4, 2019 Share Posted April 4, 2019 I replaced the broken original two-piece firing pin in my Marlin ‘94 with a stainless one-piece firing pin and also replaced the main spring with a lighter one. Been running Winchester Super X .44 Special cartridges through it and have had no problems with light primer strikes. Goes boom every time.

Does this mean that I shouldn't replace the stock main spring in an Uberti 73 by a lighter spring if I don't have a 1-piece firing pin? As I read so far it is not a simple drop in mod....

BLACKFOOT SASS #11947 Posted April 4, 2019 Share Posted April 4, 2019 Because it is what some shooters want. If they are happy with it, so am I. Blackfoot (who does not use a one piece firing pin in a Marlin.) Link to comment Share on other sites More sharing options...

Grinding down the factory hammer spring or installing a lighter after market spring is one the first mods most shooters do. Lighter firing pin springs are also available for the factory firing pin.

Thank you very much for this info! I have already received the Light Duty Mainspring from the Smith Shop, but haven't installed it yet. I will probably do it within the next days and I am a bit more confident now that it will work reliably. Link to comment Share on other sites More sharing options...
High Spade Mikey Wilson Posted April 4, 2019 Share Posted April 4, 2019 In addition to the reasons above I replaced the two piece firing pins in my Marlin 94's simply because I found that last second click when closing the bolt when the two firing pin pieces were lining up to fire annoying.

High Spade, If you were getting a 'click' from the 2-piece FP while closing the action, it was probably a good thing for you to switch to the 1-piece. Something wasn't mating up correctly with your 2 piece. Maybe a burr or something causing some 'click' sound. But anyway, glad the 1 piece is working good. Like Lumpy, I've never experienced a 'click' from the 2 piece, although I have experienced a broken spring and a 'dead' spring that had somehow lost its strength or was dead when it was installed from the factory. ..........Widder Link to comment Share on other sites More sharing options...
Billy Boots, # 20282 LTG-Regulator Posted April 4, 2019 Share Posted April 4, 2019 Not sure if OP was specifying Marlin or '73 but I will offer comment as to 1P in 73. My find in the difference in 1P versus stock 2P in 73s is not a great one and the pros mentioned above for Marlin are similar. (Not sure Blackfoot's take on "the why" is not highest on list.) I like the idea of the 1P and I do believe I can run slightly lighter main spring with excellent ignition on primers (Fed 200s). I have several of Snake Oil George's 1P FP for 73s. Snake Oil has a slightly new design which seems to wear even less on hammer as earlier ones did, and they are easier to install after his modification to your bolt. One of the few cons (negatives) many had with the 1P was that the harder firing pin protruding at rear with loaded round in chamber could cause a dent into the hammer on the hammer strike (hard firing pin/ softer hammer). If this was dissatisfaction to the user, SO would, at no charge, place a harder insert into the hammer as fix (Snake oil is that kind of guy.). I am finding that the newer version seems to not produce such a dent in hammer and I am more pleased with it. (Note: the dent I mention into surface of hammer did not seem to actually cause a problem, it just produced more of a cosmetic "flaw"....yea, I like nice cosmetics...in my shooting toys.) There are those who may offer a con opinion of 1P FP for 73s , and I would like to hear any pros and cons offered. So in a 73, Is the 1P better than OE with addition of stronger firing pin? Perhaps only slightly and more in the mind of the user....but, I am a user who likes the difference, especially the belief that I get a lighter main/hammer spring for equal ignition. Such satisfaction in my "toys" is a plus for my enjoyment of this great game/sport. If that little "piece of mind" makes me think I can go faster, well that's one of the things that keeps our vendors happy. Link to comment Share on other sites More sharing options...

Works great. My 73 has a 66 shaped extension with a 66 hammer running the 1 piece firing pin. Link to comment Share on other sites More sharing options...
