Ruger SR9 trigger work


December 24, 2007, 08:43 AM
After reading the magazine articles about how wonderful the new SR9, I begain to wonder if there was something wrong with mine because my trigger was the pits.

I tried someone elses trick of removing the magazine disconnector in the slide, but noticed no difference. What mine felt like was a gritty 2 stage trigger with a long take-up.

Internally, the SR9 looks like a Glock with the addition of a spring that pushes up on the rear of the trigger-bar. So, I went through the normal steps that I would go through to polish the surfaces on a new Glock. Still no good.

After closer examination it became apparent that the trigger bar was rubbing up against the frame of the pistol as the trigger was being pulled. I could see the rear of the trigger bar moving to the right side of the gun. Looking at the connector I could see that the angle at the base of the connector was causing the trigger bar to move out as the trigger was being pulled.

After several attempts to reform the angle at the base of the connector I got it so the top of the connector is about 1/2 the width of the trigger bar away from the bar on the safety.

The second change was to the polymer frame itself. As I ran my finger along the inside of the frame where the trigger bar was rubbing, I could feel some roughness left by the manufacturing process. I lightly sanded this until it was smooth.

The result is that I no longer have the hesitation as I pull the trigger, the gritty feeling is gone and what I'm left with is a long take-up, quite a bit of creep (with no gritty feeling in the creep), and a decent break.

If you have the same problem as I had, I recommend trying the sanding first and see if that resolves the problem without working on the connector.

Another word of caution: don't try to force the cam-block retaining pins into the frame. After disassembly/reassembly half-dozen times I had a little trouble putting in the upper pin so I hit it with a hammer. Turns out the cam-block retaining spring had slipped out of place and I really mangled it. Patience? I don't have any patients - I'm not a doctor.:)

Dear Princi,

Thanks for the suggestions on improving the SR9 trigger pull. I love the gun, but the trigger pull on mine is nowhere near what I have on my Para LDA or even my trusty K-frame revolver. I'll try a bit of spit and polish on mine and let you know how it goes.

Yeo Princi,

I pulled the slide off my SR9, and I can see (and feel) where the trigger draw bar is touching the frame. I just don't feel comfortable trying to take the gun down and polish anything. Last time I tried that with an XD9, the pistol took a long trip back to Springfield Armory!

What I also noticed was that this part could easily be redesigned NOT to touch the frame or anything else. There isn't MUCH room in there between the frame and the top of the magazine, but there is clearly enough to tilt that bar inward and stop it from dragging.

SOMEBODY (will it be you, one of us or Ruger) is going to make some money by replacing this part and giving the SR9 a really Nah-ees trigger pull.

How can so many manufacturers put so much thought into a new gun design and forget to BUILD IN a nice trigger pull?

Because nobody cares anymore.
If we didn't buy crap, they wouldn't make crap & sell crap!

I just read a test on the SR9, and it was noted that dry-firing the gun without a magazine in place will quickly ruin the factory trigger pull.

Apparently the magazine safety wears on the striker without a magazine in place to hold it out of the way.
A heavy gritty trigger pull is the result!

Perhaps too many Gun-Store Commando's are playing with these guns and ruining the triggers before they sell them?

... better than starting a new, somewhat repetitive thread I guess.

I just handled an SR9 at a local gunshop. It felt great in my hand (like my trusty 1911). Could be the first hi-cap auto I can actually shoot decently (the others just don't feel right in my hand). But the trigger pull was gawd awful horrible :fire:! Totally unuseable. It was even worse than the Turdus 94 I used to have. Looooots of creep. And maybe their is some Gritty Kitty Litter in there too. To call it a two stage is being polite. It runs into what feels like a boulder in the mechanism, and you have to apply significant pressure to finally get it to break. I bet I couldn't hit the broadside of a barn from inside in it's present state.

Maybe there is something wrong with that particular gun. There must be. It could possibly be that bad... could it? :barf:

What are your experiences?

Yes, it could!

I tried an SR-9 in a gunshop several months ago. I am a big Ruger fan and really liked the look of the SR-9, but. . .

The trigger on the sample I tried was the worst trigger I can remember. It felt like trying to push a square point shovel through a pile of granite rocks.

Unbelieveable that Ruger would go to the trouble of making a fine weapon with a sub-terranian trigger mechanism. I put it back in the dealers gun case.

As I mentioned in another thread, Ruger has called me twice wanting me to send the gun back to them. They went though the distributor to the dealer to get my unlisted phone number.

I finally called them back and told them I was in and out of the country and it would be difficult for me to send it to them and have them return it while I was home to take posession of it. (Don't want anyone else in the house handling my guns except in an emergency).

What I'm really afraid of is now that I have the trigger where it is half-way decent I don't want them screwing it up further. I can just imagine getting it back and it having a gritty 11lb pull.

So they build a gun that has a lousy trigger pull. I'm okay with that, but really frosts me is the articles that I read in the trade magazines that praised the trigger pull. Did they send the testers a case of Scotch with each SR9 they sent them? Wait, aren't they in Arizona? Maybe it was a case of Tequila.

For those still interested, here's a link to a very detailed "HOW TO" thread found over on Everything from magazine to trigger disassembly.
