just bought aq used mp40 shield. magazine has such a stiff spring, I can only load 4 or 5 rds with comfort and trigger has at least a 10 lb trigger pull. Is this normal? As it is the gun is almost useless and far inferior to my XDS

You may have gotten a Massachusetts compliant model.

An Uplula mag loader will resolve the Shield mags and their stiff springs when loading. As for trigger pull weight i cant comment on that part. I dont weigh the pull on any of my guns I just take them to the range and shoot them.
 
funny that you compares it with the xds, haven't seen any trigger worst than that.

My XDS has a great trigger, the gun and 7 rds of 230 gr .45 hollow points are a little heavy for everday carry, so thought I'd try the MP40 shield. So far I'm unimpressed!
 
If the trigger is as bad as you say it could very well be the MA compliant with the mandatory 10lb trigger. You could look up the model to tell. Apex makes a trigger kit that would help.

Hmmm, a 10lb trigger? What did you use to measure pull weight? If it just feels heavier than some other gun you have, it's probably not 10lbs. Of course if you live in MA, it has to be a 10lb trigger from the factory.

Lots of people have trouble loading the mags. They are tight on purpose. It will just take time. Consider buying an UpLula.
 
I measured the triggers on our Shields. PC versions were 4.5-5lbs. Non-PC are right around 6lbs.
 
If you got the box with your used pistol, check the SKU number on the S&W website to see if you do, in fact, have a MA trigger. If you don't have the box, S&W customer service might be able to back check to determine the SKU and the appropriate trigger weight.

Having started to work with revolvers again, the length of the trigger stroke (on any handgun) and the quality (smooth or rock garden) is much more a problem for most than the weight.

If it does have the 10 lb trigger mechanism and you aren't required to have that, check with S&W to see if they'll exchange the parts for non-compliant parts. I expect S&W would be willing to at least take a look at it under their warranty/customer service program. If not, I'm sure some competent local gun smith can do the parts change at moderate cost. Emphasis on the "competent".

That sounds about right. I've shot my PC and a friends standard Shield side by side and without measuring trigger pull that is what I would have guessed for both. A noticeable difference but not huge.
 
Change out the trigger yourself. I know you probably don't want to spend any more money on the gun but then apex trigger kit is a great upgrade. Or look for parts to lessen the pull weight. The shield is a great fun, I own a model with factory night sights. But I kept the stock trigger. Its not a gun id enjoy shooting at the range all day so I didn't bother. I put an apex kit in my 2.0 and that gun is amazing all around
 
One, try leaving the magazine loaded for a few days. It will help if you obtain a Upula Magloader so you can load the mag to its max capacity. It certainly made mine easier to load. Then unload and reload a few times and leave loaded again. This is something I do with all my magagzines.

The trigger on my .45 Shield has smoothed out nicely after about 50 dry-fires, followed by cleaning and then lubricating the trigger mechanism. It improved so much that I doubt if I will use the Apex sear I had already purchased.

After that, I'd contact S&W if you still not happy.
 
We are all sensitive to triggers in different ways and evaluate them differently.
I couldn't ask for a better trigger on my 45 Shield after installing just the Apex sear.
When you are at a fairly busy gun store like the one I have in my area you will find the trigger on the display model is always nicer than the new one you get in the box when you purchase because the popular guns on display are cycled several hundred times or more already:) If I really like a trigger on the display model I will request it instead of a new one in the box!

IF you really have. 10# trigger pull, the first and cheapest thing to do is to put in a standard trigger return spring that will reduce the pull weight to ~6#. It won’t do anything else but lighten the pull.

Swapping the spring out is easier with a slave pin and while not terribly hard, for a first timer it is a little complex. A good gunsmith could do it for his minimum charge.

Shields are good guns. You may have unwittingly bought the Mass. compliant version referred to, or your perception of the actual weight is over stated.
 
I bought a loader years ago for a .45, got it out and it says on the side 9-.45. tried it and it works great.
 
just picked up my new MP40 40 cal Shield. charging my mp 40 shield is not as easy as pulling the slides on my other semi autos. would changing the recoil spring alleviate some of the needed effort.
 
Small guns with short slides and high-pressure calibers must have have a recoil springs. If you change out your recoil spring to a lower weight, you will probably have malfunctions.

Learning to use technique more than muscle to pull back a slide will usually make the process easier. Practice with the gun unloaded and no magazine in. Turn slightly sideways favoring your a strong side with your gun in your strong hand. Take your other hand and put the bottom of the palm on the near side of the slide and your fingers over the top on the right rear of the slide. Push the gun away from you while pulling back on the slide. This push pole technique will usually handle a stiff recoil spring just fine.

Also, if the gun is new, the spring will be a little stiffer than when it is broken in after two or 300 rounds.
