    Took my SR45 to the range and experienced some what I guess I would call light primer strikes. My SR45 does not have any FTFs or FTEs, no stovepipes, and the slide locks open on the last round. I have read that some SR guns (especially the SR45) can have light primer strikes.

    From reading online, the fix for the light primer strikes seems to be getting a Galloway Precision heavy striker spring.

    https://gallowayprecision.com/ruger/sr/heavy-striker-spring-for-ruger-sr9-sr9c-sr40-sr40c-sr45/

    Has anyone had experiences with using these springs? Galloway recommends a smooth it kit to remove the added pull weight of this spring on your trigger.

    Thanks.

    I don’t have a fix for you, Galloway is probably right, but I experienced the same thing when I had an SR45. I sold it not long after I discovered the problem. It was a smooth shooter too.

    I really like the pistol, it feels like a single stack 45. I will try the spring and see how it works.

    I don't know anything about those springs but I was wondering. Have you ever cleaned your striker channel? If it is gunked up that might be the cause of your issue.

    Yes, twice.

    Once when I removed the magazine disconnect and just the other night. This time I used a .22LR bore brush down in the striker channel.

    The problem with the SR45 that I’ve been saying for years is that it’s underspung. I had this happen to me a few years ago and I cleaned the striker channel out and removed the magazine disconnect and all has been well as far as the light strikes go. Then I noticed other areas undersprung, so even though I absolutely love the way this gun shoots I cannot trust it for self defense of any kind and keep it as a range gun. Just out of curiosity do you keep your striker cocked all the time? I’m interested to see what the new springs do for you as well.

    I HAD that problem with my sr9c and it went away after replacing the striker spring only. Mag disconnect isn't going to help and as far as the striker channel being dirty, I've never seen enough dirt there to be a problem. Just change the spring and you'll be fine.

    Mine was full of crud. I did the pen test. Before I cleaned out the striker channel my pen would bounce, after I cleaned the crud out my pen would shoot out. This was all after I took the mag disconnect out. Somehow lubricant got into my striker channel trapped crud

    I assume you installed the Galloway Precision striker spring? The manufacturer says that the spring gives about 20% more oomph to the striker when it strikes the primer. Did you have a heavier trigger after that?

    I didn't notice any change in the trigger pull. They also recommend the spring and plastic housing. I didn't see the need for the extra part and expense. I just replaced the spring and the light strike problem went away. I think it was $11.The other problem I had (now we're talking a sr9c 9mm, but I see the light strike happening in a few different model Ruger's) was quite a while after and unrelated was the gun stopped resetting the trigger after random shots. I sent it in and Ruger replaced the whole trigger mechanism, trigger,trigger bar,etc. They test fired it 50 rds. and I ran 150 through it without any stoppage. I sold it shortly after only because the gun sat in my safe more than not. I traded it for a Springfield XDE 9mm.

    i put a 20 pound recoil spring in my ruger sr 40, the factory one was wimpy and at 18 lbs
    the trigger pull was to heavy for me at 6.5 to 7 lbs so i replace it with a ghost 3.5 pound replacement much better now:thumbup:

    if you replace it with a stronger striker spring the trigger pull will increase and you will more likely want the ghost trigger kit installed to bring it down to a 3.5 or 4 lb pull

    Galloway Precision recommends you install their smooth it trigger kit #4 if you install their heavy striker spring. Looks to me like the #4 kit is just a bunch of polished parts.

    What Galloway precision states is the following when buying the heavy striker spring.

    https://gallowayprecision.com/ruger/sr/heavy-striker-spring-for-ruger-sr9-sr9c-sr40-sr40c-sr45/

    Looking at the Smooth it kit 4, it looks like they added a stainless plunger and some polished part.

    My SR9 light strikes during its 1st range session ceased after I cleaned out the striker channel.
    My SR45 has had no problems.

    I had a sr45 that absolutely would not run with my reloads. I would get around 5 or so light strikes per 50 rounds. My reloads would run in 5 other 45acp pistols but not in the ruger. I tried different primers and a heavier striker spring but nothing worked. It seemed to run ok on factory ammo. I sent the gun back to ruger 3 times but it still wouldn't run my ammo. I gave up and now my stepson owns the it.

    I ordered the heavy striker spring, trigger reset bar, and stainless striker indicator from Galloway Precision. I can polish the plunger. Hopefully this will cure the issue of light strikes.

    Maybe drop a bit more powder or try different primers.

    I gave it to him. He doesn't reload so maybe he will have better luck. He's had the gun over a year and hasn't shot it yet.

    i heard of many of folks never shoot their guns pistols, they buy them and put them away, crazy? they have little idea of the recoil of a 45 cal and could hold it limp wrest and could fly right out of their hand the first shot..

    That's why when I introduce someone to shooting a hand gun I will always put one round in the chamber to see how they handle the recoil etc. Don't need it spinning out of control and shooting me or someone else there or even themselves.

    The funny part is my stepson has a membership to an indoor range for a couple of years and he hasn't gone shooting there yet. He also has quite a few firearms, he just doesn't go shooting. Now me I go at least twice a week. :)
