This really puzzles me. A stock 5906 with the safety on shows 3/4" trigger movement measured at the tip in double action, 3/8" in single action. I have to wonder if/what other internal mods have been done. Doesn't puzzle me enough to start doing parts swapping.

It's your money and choice. In your place, if you wanted the cocked & locked option and no mag safey, I'd be inclined to swap the current piece for one that hadn't been "improved". Then, you could remove the magazine safety plunger spring, slightly modify the angled lower leg of the sear release lever (or buy a replacement and modify that, saving the one that works correctly) and you'd have what you want with no mystery mods.

To the gent who commented about getting a signed acknowledgement of the modifications: proper, quality trigger jobs don't alter the operation of safeties from factory specification. THAT'S why the buyers agreement that he's been informed of those particular modifications is a best practice. But, it's your retirement fund, future earnings, cars and house.

I'm going to take this 5906 to the range tomorrow and run 250rds through her. I'll update when I get back home. If everything goes well tomorrow, I'll run another 250 through it Friday or Saturday. I'm an old guy and 250rds makes my eyes see extra dots on the front sight

At one time in the past, I thought any mods done to a firearm were taboo, but that wears off after you do a few mods yourself and learn thoroughly how each weapon operates. This is my first steel S&W, so I'm learning about it fairly quickly. Thanks for the ideas and solutions.

Ok, in DA, with the safety lever down/engaged, there's about 3/4" of trigger movement till it stops. There's zero hammer drop or movement. In SA, lever down, there's a good 1/4" of movement till it stops, no hammer movement or hammer drop. I thought it was an 1/8" before, but that was wrong, sorry.

OK, my concern really wasn't that your piece was altered. The way you initially described how the trigger worked had me wondering just what in the heck could have been done to achieve that. When I ran a shop I had several cases where people brought me altered guns where my advice was to sell the gun back to the shop/"gunsmith" that committed/sold the atrocity and buy a new one. Cost of proper repair would have been prohibitive.

It's likely that the only things that were done was altering the sear release lever and removing that itty-bitty spring. No way to be certain without a detail strip of the frame. Picking up a new sear release lever just to have on hand would be cheap now in case you decide you need one in the future.

Hope you like it.

I just got back from the range. The 5906 ran 250rds of Blazer Brass 115gr and 124gr flawlessly. The SA trigger pull feels like 5-6lbs, crisp and no creep. The DA is smooth and feels about 10lbs with no stacking.

After doing a little more research on the mods made to it, I'm really not concerned that they compromised anything else with this handgun. The Sear decocking lever was reshaped a few thousandths, and the magazine disconnect spring was probably reduced in length, nothing else was done. Both mods do not impair or degrade the safe operation of this handgun and are easily rectified if you want them back.

One of the target pics from today at ~7yds. I have to get used to the heavier trigger on this 5906.

I believe your sear release lever was altered after leaving the factory, but this is pure opinion on my part, based on the appearance of the lever in the photo you provided.

This is the shape and contour of an unaltered sear release lever. Notice how the top profile is flat, and differs from the one in your frame, which has a rounded profile on top....



I agree, the sear lever was rounded on the top to allow it to engage the safety but not the decocker. I just ordered a new stainless sear lever and magazine disconnect plunger spring, but that is for future use when it moves on to a new destination. I prefer not to have the decocking or magazine disconnect function. Here's a pic of the lever I ordered:

Ran 200rds today with zero issues, so that's 450rds so far with no functional problems at all. This is a rock solid sweet shooter, but the SA trigger pull is a bit too heavy to get great accuracy IMO.

Took it out again today and ran another 150rds for a total of 600 now. Not to jinx it, but it's been 100% reliable so far with nothing compromised. I have another mag coming this week, so additional shooting will have to wait till I receive that new magazine. No pics this time.

I received a new Mecgar mag and a new factory 14lb recoil spring, so off to the range today to make sure they both functioned well. No problems running 200rds, so that's 800rds now with zero issues.

If there is only one thing the third gen S&W pistols are known for, it is reliable functioning.

Well its actually set up like the PPC9s with the decocker in the down position acting as a hammer block.
Some agencies made officers use the decocker in the down position as a safety, LASD for one. LAPD's issue holsters actually had a small leather piece that pushed the D/C on 92fs and 3rd gen S/W into the up position when you snapped the thumb break.

My brother in law has a 659 with a similar issue. The safety doesn't usually drop the hammer unless its pushed very hard and sometimes not at all. If I squeeze down on the frame the hammer falls. He is the original owner, very low round count and no work has been done on it. Whats the fix for this?

Fit a new sear release lever.
