I have an as new 336a that my gunsmith can not get a decent trigger on. Midway has wild west triggers that they clain will get a crisp 2-3 pound pull for $79.99

Not a 336, but I put one on my Guide Gun. Big improvement in my view. I also replaced the extractor with the Wild West version.

Ditto Jim's experience. I have the WWG trigger on my 1895CB which, of course, has the same action as the 336. You don't get very much metal for your $79.95 but it DOES work great. Pull is now a consistent 2.7 lb. with a nice clean break.

I've installed two for customers.
Both worked as advertized but one had to be stoned down on the sides to get it to fit.

I've done litterally a couple of hundered trigger jobs on Marlins, what problem is your 'smith having? The only reason I installed the ones I did was both customers brought me the gun and the trigger unit and basically said, "Here, install this please."

He thinks he can't safely get it below about 5# pull..It took me 5 years to find the gun & it does about 1.5" with walmark federals & 3" with my handloads.

I set them up for dedicated cowboy shooters with 1.5# as a custom item for trusted customers and 2-2.25 pounds for those that have been shooting a while and around 3# for the cowboy shooters that are brand new. If you get much less than 20 oz they start developing hammer follow when the bolt slams shut. (At 3-4 rounds per second in a lever gun, yes, the bolt is slamming shut.) I've been running a 22 oz trigger for 7 years. The Marlin trigger is very easy to make any poundage your heart desires and keep it safe so it won't "bounce off". Its a great design.

WWG makes a great trigger -- my smith had it installed in my 1895 cowboy in minutes, it eliminates any "flop" and it has a nice, light, crisp pull.

I put one in my 50AK GG along with a lighter spring kit and it made a WORLD of difference. I'm no fan of WW Guns "customer service", but admit this is money well spent. The trigger is honestly crisper than any of my bolt or double guns. My RWS air rifle is the only one that's better.

The only issue I had was that it has a Dave Clay medium-sized lever loop (for gloves) and it does move the trigger position slightly rearward (that's how it take up the slack). I had to give the lever a few strokes with a file to get enough clearance, maybe 1/32". It's a stainless gun so didn't matter, but might if you have a blued nonfactory lever. Great stuff though and I only wished I'd done it sooner.
