So, I've been intrigued by the SD9/40 since they first came out, with the black slide and tritium front sight. The cost was to close to the LE price of an M&P so I never followed thru.
Then there was the stigma of the sigma, of which many said they were the same gun, or close.
A few months back, I was able to buy a "used" one for $150...it was un-fired and still in the plastic bag, in the factory box.
It is the newer style, that lacks the black finish on the slide and the tritium front sight.
I have only handled a Sigma once, around 2000, I recall the grip feeling good, but the trigger was extremely heavy. So, I can not speak to any differences between the two. A search of the "errornet" reveals the trigger system is different, and the have received some good reviews from those that actually own them. Including one 2K round challenge popular on another pistol oriented forum.
Out of the box, size wise it compare favorably with a G19
This is a G19 placed on top the SD9
The trigger shoe is curved and hinged like an M&P, and I believe the Apex part can be fitted.
I do not have a trigger scale, but the out of the box weight compared to an unbroken/worn in "+" connector in a formerly issued G22. I think the factory lists it at 6.5#.
I'm also not one to talk about smooth, icicle like breaks or carrot like, creep, etc...it's heavy or light.
It included two 16rd mags, in 9mm, that are Sigma mags with a different floorplate. However the sigma mags lock in place and work.
The front sight is steel w/ a white dot, the rear is plastic with dots. The plastic "seems" higher quality then the plastic used on the Glock sights.
There are front cocking serrations
There are "Stippled" finger pads for the trigger finger, and off hand thumb.
I do not have any pics of targets..or I do they just aren't labeled....but, shooting "freestyle" two hands at 25yds on a NRA B8, I was able to shoot into the high 80's low 90's for 10rds. The heavy trigger was detrimental in the respect.(for comparison, I can shoot my M&P40 w/ apex kit and KKM barrel, tuned 1911s, a G22 w "-' connector and Barsto barrel...into the high 90's this way.)
Additionally, while the grip has some texture, it really was not enough for the heat of a SC summer. So, I was able to trim some TruGrip for G19 to fit well enough, to help in that regard.
Apex sells a simple kit, which is just different striker, striker block and trigger return springs. After reading about some failure to fire with the Apex striker spring, I chose to leave that out. The kit did bring the weight down some, which made little if any improvement on the B8's...however, what it really did was make it easier to shoot similar scores.
I've got only about 600 rds thru it right now. IIRC there was one failure to extract with winchester white box 115grn ball. Otherwise it has shot, Winchester 124grn NATO, Magtech 115's, Lawman 124's, Federal AE 124's and 147's, some Gold Dot & Win Ranger 124's, and some of the federal in the white box 147grn JHP..supposed to be HiShok's I think...contract over run(?), with out issue. I recall Winchester White box having some reported issues in the M&P and maybe other 9mm's as the rim dimensions maybe on one end or the other of the spec. Either way that is the only malfunction so far.
The gun will fit in a full size M&P holster. I was not able to fit it in a Raven Kydex for the M&Pc as the end is rolled over...a little heat and some coaxing might get it to fit. It fit fine in a Wild Bills leather Vertical Scabbard, of course with some left over at the bottom.
The sight dovetails are the same as a M&P, and I've been thinking about replacing them, but so far I'm just waiting on a take off set from an M&P or otherwise tried and discarded set showing up somewhere.
Some things I like about it vs the G19
I prefer the hinged trigger of the Smith's, though these days I'm inclined to believe all these trigger safeties are just gimmicks.
I prefer the feel of the grip to the Gen3 G19, it also has a shorter trigger reach, which is good for me. I've only handled Gen4's in the gun shop, a while back....so I can not compare the two.
The slide stop is of a nice size, and made reloads easier
The backstrap is slightly extended, similar to the extended grip plugs that used to be available, and the hole does not go thru to the inner workings.
SD v. G19:
Now, I'm not saying we should all run out a buy one of these, but for some, it may be a decent alternative.
Mostly a wash, as most switched on people will change both brands out. For those that this gun is really aimed at, I think the steel front, and better rear, are a better set up then the plastic glock sights.
If the Gen3 or 4 doesn't do it for you, the SD grip feels very good to me. SD specific grip tape is available if needed. Otherwise, to me the traction feels no worse then a Gen 3 Glock, the RTF frame is a different deal though, and I really wish S&W had a comparable offering.
Again the trigger reach feels better for my small hands, but not sure of a Gen4 Glock. If you are like me and prefer the curved & hinged trigger, there it is. If not, the Apex offering should fit.
Weight is still higher then the Glock, but not un-manegable. A fellow LFer, remarked he liked it better then the factory Glock trigger after the apex kit was installed. But, thats it...I'm sure some one could polish and what not the internals to help out, but there just aren't many factory options for it.
Its silver/white whatever you call it. So if the two tone things isn't for you.. a can of AlumaHyde is cheap. I think a local guys charges 75 bucks to cerakote just a slide.
It does have front cocking serrations, if those are for you.
It has universal or picatinny rail on the dust cover, so a SF X slides on fine.
-A simple price comparison at a place like Academy, or a LGS, puts the SD's at about $325, and a G19 at $550. Glock mags are about $20 and SD's...$35
I've seen SD's on sale for about $275.
For some the price difference is a big deal.
And thats really where it is....if money is a serious issue, I would recommend this, and I have to a friend.Other then a used G19 of unknown pedigree, what else is there? I would take this over a Taurus or other questionable companies offerings.
The average guy or chic that wants a gun around, but isn't a gun guy....not at the level we are, is not going to look around for used G-lock, or know what to look for.
For the money saved over a Glock, the buyer can buy some OK enough carry gear, some ammo, perhaps another mag. If they shoot it once in a blue moon, they'd be ok. If they shoot it more then that, they can make some simple upgrades with the Apex kit, some tritium sight & grip tape.
If they really get into it, a local guy can still stipple the grip, and maybe paint the slide....all of which can be done over time.
I also think it compares well to the used K frame 38 that is often recommended for this type of shooter.
Me, I was intrigued by them & liked the idea of a "project". I was able to get it at a good price, and can upgrade it a little at a time,...or not.
I kinda like it.....anybody got any M&P sights laying around?
