Excellent workmanship and single action trigger. Worst double action trigger I've ever felt. Real let-down.

This is surprising to me. If it doesn't perform as you hoped after shooting it some, I'd contact Kriss.

I find the SA trigger to be extremely good, and the DA trigger similar to SIG's in weight, but a little smoother.

Yeah, my DA is easily on par wih my 228, 245 and 239. The SA is much better. Sounds a bit unusual, not what most of us have experienced.

I think out of the box and lot of the Sphinx guns DA triggers are too heavy but very smooth. A simple 5 minute spring change with a CGW kit or Wolf CZ Compact hammer spring changes it and puts it in the 8-9lb range depending on your gun.

Pretty much mirrors my experience as well.
The DA pull is good and can easily be mastered with a little practice.

Sphinx could have easily dropped in a lighter spring but i'm sure the #1 priority for this pistol is to ensure reliable ignition with a wide variety of ammunition. I've seen my share of pistols where someone puts lighter springs in a pistol and made it unreliable with certain types of ammunition. No telling how many people have had action jobs done and never gave the ammunition a second thought afterward.

In general, there is a pretty experienced bunch of folks here that understand this and thoroughly test their guns after making spring changes. Nothing wrong with a nice light DA trigger as long as it's reliable.

DA is perfect for me in a carry pistol. It's very smooth. 0 zero complaints in any area of the trigger and I usually require some smithing. The weighting of the DA is very nice in the pistol for some reason. Lends itself, very well, to staging.

I want a pair of the Standard Blacks bad.

It is my understanding that prototypes shipped with a lighter mainspring but testers believed the trigger was too light.

IIRC there was not talk about ignition issues. I personally wish they had shipped it with lighter hammer springs.

I can't imagine why they would come to those conclutions if reliability wasn't an issue. Maybe the Lawyers thought someone would accidentally pull a 7 to 8 pound DA trigger. Big Grin

I have a Beretta Elite II I sent to Ernest Langdon back in the early 2000s and he did a level II competition action job.
The DA pull is around 7 1/2 lbs. He didn't recommend using the pistol for self defense and recommended using Federal Primers. The pistol would shoot several kinds of ammunition without issue. That is until I recently shot some Speer Lawman. I had a few light primer strikes out of the couple of boxes I had. As a reloader, I knew CCI/Speer had some of the hardest primers in the industry. Federal having some of the softest. I know every gun is different so testing it with what you carry is a must.

Have you tried David's (CGW) $20 spring kit? A lot of happy campers have them in their SDP's.

This precisely why I want a DA/SA for carry, whether Sphinx or SIG.

For range use I want a light, crisp trigger, but for carry I want a 10# DA pull. My accuracy suffers very little, and my piece of mind is close to that of having an independent safety.

When I am shooting the Sphinx just for precision, the SA trigger is nearly in the same category as my P210 Legend, X5 L-1, and customized 1911 with a 3# trigger.

I, obviously, am not a candidate for Glock or SIG P320 style pistols. I prefer DA/SA or SA with safety.

Safeties are completely out for me. DA/SA is my preference and I have a special passion for this trigger type. I can run a striker pretty well also, If need be. But I prefer that DA/SA.

Yes I have one of his kits in my Compact the Subcompact is stock.

I also tired the Wolf CZ compact springs but got ignition issues with harder primers like CCI. So I took it out.

Good Morning, WVsigP228

After installing one of David's kits, how much of a difference did it make?
What is the DA pull weight?

The CGW kit in the compact got me a trigger pull of DA=8.9 lbs SA=5.4 lbs. With the Wolf springs it was closer to 7.12 lbs but even with the 19 lbs spring I was getting a few light strikes with CCI primers so I opted for the CGW kit. It is well made and worth the $20 IMHO. Whenever you change hammer springs it is very subjective to the gun. Other people report no light strikes with as low as a 17lb CZ compact spring from Wolf.

My sub which went back to the factory for barrel and slide stop issues came back considerably cleaned up. It is smoother than when I sent it in. Stock it is DA=8.13 lbs SA= 5.12lb.

I did not install the reduced power lifter arm spring. I have not had the time, The other parts go in withing minutes.

Thanks WVsigP228,

The CGW kit sounds pretty good and will give it a try in my Duotone.
It's pretty much a range gun so light primer strikes shouldn't be an issue anyway.
I have always used Winchester and Federal primers when reloading and stay away from CCI. Years back, I bought a case of CCI primers and had nothing but trouble with my Wilson Combat Accu-Comp LE. It had a 2 lb. trigger. They are good reliable primers but don't work well for competition guns IMHO.

Well I finally got to the range with my Sphinx subcompact and ran 250 rounds of Federal 124 grain through it. Perfect all the way, and very accurate.
Looking forward to getting back and shooting another 200-300 rounds next week.

By the way I need 2-3 more mags. Anyone know the best place to get them? TIA.
