    P220 DASA Improvements

    basicdon1957 (verified owner)

    Recently purchased and installed GrayGuns 1) Short Reset Trigger Kit, 2) Custom Strut System, 3) Modern Classic Hammer, and 4) Dual Adjustable Curved Trigger on my P220 DASA Sig Legion. Bench testing on five group averages showed the DA went from 9lb-1.6oz to 8lb-1.5oz — the SA went from 4lb 8.2oz to 2lb-5.8oz. Actual shooting results were unbelievable. The P220 now feels like a totally new machine. I think it will far outshoot any of the 45s I currently own, and (ignoring magazine capacity issues) is probably going to be my favorite 45 to shoot ……. This includes an FNX, FN545, P220 SAO, and several 1911s. In my eyes, whoever designed and built these changes are currently on a pedestal up in the clouds next to the big guy himself (JMB).

    Another quality part from Grayguns.

    eveningcop20 (verified owner)

    The Modern Classic Hammer was another fantastic upgrade from Grayguns. I installed this and a the flat trigger in my Sig P229 Legion in 357sig. I had previously installed the Sig P series Strut System.
    The trigger is butter smooth, no stacking. The short reset is nothing short of phenomenal.
    I also have to give a great review on the Sig P239 hammer spring I previously purchased. The only place I could find one.
    The quality Grayguns parts added to an already great pistol, and made it even better.
    I’m now looking forward to doing the same to my Sig P220 Elite.

    Perfect hammer for anyone considering carrying their P-series Sig, or who is looking for an upgrade to the stock part. The finish is excellent, and the overall design is truly a modern remake of a classic.

    Great add on for my P-226

    ozzie80 (verified owner)

    After adding your enhanced Trigger and Trigger bar plus the heavy recoil rod and spring the Hammer was just another ideal piece for this 226. I loved the performance derived from using your parts and the pistol is a pleasure to shoot.

    The Better Hammer

    jlmac (verified owner)

    Beautifully machined and finished, this DA/SA hammer will enhance the function of any classic P-Series trigger.  It’s even better when installed with Grayguns’ custom strut system and their short reset sear.  Installed together, these parts result in superb trigger action. And, just to pile on to other commenters here, the skeleton rowel spur design looks downright terrific, lending a custom appearance to any pistol. Seen here on a P220-5 10mm Auto.

    Hammer time

    Steven Millhouse (verified owner)

    Replaced factory P229 hammer with this. I also upgraded the struts and springs at the same time so I can’t isolate performance improvements. What I can say is I appendix carry and this hammer is way more comfortable to cancel compared to the factory.

    The difference between an A and an A+

    johnfmerrick (verified owner)

    All my SIGs have a variety of GG components but I have one favorite P229 in 357 SIG that had everything except the GG hammer. I installed it yesterday. I took before and after readings using NRA weights for the SA and a pull gauge for the DA. The installation of the GG hammer took off .5 lb from the DA (it went from 10 to 9.5) and .25 lb off the SA (it went from 3.5 to 3.25). The DA was slightly smoother and also seemed a tad shorter but that could have been my imagination. The gun was great the way it was, so was the extra $124 worth the small gain? Well, it’s that effort and money put out to get an A+ result rather than an A. So if getting the best action job possible is important to you this hammer is worth the money. And it looks great!

    Perfection

    Randy Johnson (verified owner)

    I recently converted my P226 Nitron to a “Legion” by replacing the grips with Hogue Legion grips, low profile controls and a short reset trigger. This hammer was just what I needed to create a unique look. On the practical side I find it easier to thumb the hammer due to the unique geometry of the ring. I’m extremely happy with my purchase.

    Excellent upgrade

    donald.wm.parker (verified owner)

    I installed this on a P220R that I had previously sent to GG for the ELS trigger installation (which is nothing short of awesome), and I couldn’t be more pleased – and I definitely learned many lessons regarding Sig hammer fired disassembly/reassembly… I’ve only been able to function check with snap caps, and heading out to verify performance this weekend. Now, if GG would make a version of this hammer for my SAO Legions…

    Functional and looks damn good too

    brianfortier413 (verified owner)

    As with everything I’ve ever order from GG, this hammer perfectly designed to for my P226 and improved not only the look but the functionality of my pistol. DA feels cleaner on the pull.

    Must have part for your Sig

    John Telford (verified owner)

    This hammer is exactly what a classic Sig pistol needs. The ergonomics on it are excellent and it improves both single and double action pull. The double action is especially smooth and I expect an increase in first shot accuracy because of it. The only fitting required for my installation in a Sig P220 was to stone the side of the hammer strut so that it moves freely in the hammer slot. Quality, fit, and finish are excellent. I plan to put one on my P226 next..
