"Fire Starter" Titanium Firing Pin for Ruger MKI, MKII, MKIII, MKIV & 22/45


 At a Glance:
  • Titanium is 40% lighter than steel
  • Helps reduce lock time for higher accuracy
  • Non-corrosive and highly durable

The TANDEMKROSS "Fire Starter" Titanium Firing Pin for Ruger® MK™ Series is a drop in replacement for the factory firing pin. A titanium firing pin is lighter and moves faster than a heavier steel pin. This reduces lock time and allows the gun to go off faster which can help to improve accuracy. The lighter titanium pin is resistant to mushrooming and will provide repeatability with positive primer strikes. With less deformation of the casing due to the lighter weight of the firing pin it can also lead to better extraction. The stability of titanium over steel makes it an ideal choice of material when operating in extreme heat or cold conditions.

    Firing pin

    Posted by Gordon Smith on 6th Oct 2021

    As far as I can tell after about 500 rounds it works great. I have an old Ruger standard with a MKIV bolt and anyone that says it won't work in that standard is badly mistaken. Can't lock the bolt back,and you can rack a round on safety. The firing pin makes a nice strike mark and never failed to fire. Thanks for a high quality part. Gordon

    Firing Pin review.

    Posted by Tom Marshall on 6th Jun 2021

    I have 6 RUGER MK IIIs and MK IVs. I routinely replace ALL the firing pins in my RUGER MK IIIs. It is inexpensive and EZ to install. I have never had issues with any firing pins. When I have had FTF issues I have blamed the main spring or the ammo. Always appreciate the TK videos and innovative offerings. Thanks, TK. Tom Marshall in Georgia.

    I have installed these in both my Ruger .22s. I have no problems with deformed cases and extraction problems now.

    Fire Starter Firing Pin

    Posted by David on 18th Mar 2021

    Bought 2 of these for my 22/45's, only had a couple chances to try them out, but they seem to work fine. The original firing pins weren't too worn yet but I wanted to get them changed out before I have too many problems.

    RUGER 22/45 mk3 firing pin fix. Failure to fire

    Posted by Jim Castanaga on 18th Feb 2021

    The old oem firing does last a long time. I was a little skeptical that titanium may not hold up as well as the oem firing pin. I didn't have anything to lose so I bought this and it fixed my light strikes 100% it was noticeably lighter too. This firing pin looks as perfect as the day I first installed it. It literally makes craters! I will safely admit Tandemkross Titanium firing pin holds true,bit is tough!

    Firing pin

    Posted by James Robertson on 18th Sep 2020

    I’ve had my 22/45 MKIV for a few months. Only one light strike. Read about this problem and immediately bought this pin. I keep my fire arms spotless, and I’m being proactive on this issue. Don’t want this happening to me at the range. Excellent piece! Easy replacement. Thank you Tandomkross!

    Titanium Mark II Firing Pin

    Posted by Greg on 27th Aug 2020

    Installing this firing pin made a noticeable difference in the way my Mark II operated. You can see the imprint on the .22 shell is deeper and crisp. No more light strikes. Great product. I got 32 years and 1000’s of rounds through the original and expect my grandson will be shooting this pistol 32 years from now.
