Nicely done by Primary. I didn't find out about it in time before having someone else do it. Looks more elaborate and more weight-reduced comparing with what I have done on my slides. The 43.8 weight actually might be a tight squeeze since the pic is with a regular poly base pad. +5 base pads are usually about 1 oz so you might be just 10 grams or so under the weight limit. I'd consider a polymer guide rod and some attention to grip's selection.

My experience, and experience of a number of my shooting mates, suggests even less, actually. My first unit broke twice, at 3 and 5K respectively. #2 and #3 are doing ok, both under 5K so far. I am aware of some units going between 10 and 20K but I don't know of any DPP owner whom I know personally and who hasn't broken a DPP.

My only concern is that I fully expect any DPP to break at some point within 10-15,000 rounds and I am concerned with Leupold not honoring their warranty if they found any sign of tampering. I don't know for sure what they will or will not do, but I know for sure it is only a matter of time before I have to send yet another one back for repairs.

Not to side track the discussion, but. I've heard that before, I have two different plate systems for DPP, the Unity adapter and Henning in-dovetail plate, and I can't mount my J point on them.

While I don't have huge hopes, this is the reason I am not having anything milled for anything until I see the ACRO.

As mentioned, Tanfo is larger than CZ which is why I initially went with Stock 2. After losing a battle with two of those 2016 guns, I moved to Shadow 2 and its grip is smallish. I asked LOK grips to make me extra fat bogies, no palm swell, just straight fat grips, and that solved it for me.

Why not to extend the same line of thought to Shadows as guns in general? I mean, they are purpose built game guns with no real practical use other than competition, between weight, manual decocking, type of sights used etc. What's a principle difference between a purpose build competition gun and a purpose built tuned competition gun? How would we address various degrees of modification done at the factory before guns reach consumers like Tanfo Extreme line vs regular Tanfos? I started my competition experience in IDPA and USPSA shooting a pistol that was not competitive with anything that people use in the sport, trigger jobs or not. It didn't add anything to my experience with the sports, just added an insult to the injury imposed by my skills, or lack thereof

There is a short reach trigger option for CZs.

My second Shotmaxx, S-2, died last week. I don't exactly remember how long I had it for, maybe 3 years? The first one died after moisture got into it. This one stopped beeping although it still records shots. Personally I continue to think of it as a mediocre timer with only one redeeming quality of an accelerometer option for public indoors range use. I think the watch and stop watch are useless, buttons are too easy to engage on accident, the spy mode never worked for me, and it did get false counts at times. I won't hurry to pick up a third one.

Thanks, that's good news.

Can't say I feel a lot of difference. Statically it feels less front heavy, more like Stock 2. When I shoot it, I don't notice much. It took me about 5 months to get this done. Finding extra slide, then it went through 3 different shops (in retrospect, two could've done it), then I decided to mill the frame, then - fortunately before the work was done - my first Shadow 2 broke that internal piece and had to be replaced, etc. So for the last 5-6 months I've been shooting Glock 19x, and I just don't remember how unmodified Shadow shoots. Right now I am working my way back in from Glock to CZ so I've not shot a ton of standards to see if there is any historical difference. What I see on sights, er, the dot, looks how I remember it before milling.

Gunsmith who did most of this isn't looking for work so he'll remain anonymous. The slide is directly milled for the DPP and I chose to keep the housing on. I also use custom thick Lok grips. With a steel guide rod in, it is 44.2 oz with a Henning extension mag. This is a spare slide that I got from eerw so I can still play in Production using the original slide. Thank you, Stuart. I have another frame that has been lightened the same way; with Henning mag it clicks exactly at 45 oz. With costs associated with buying a second slide and getting the work done, I am also hopeful for an OR factory offering.

Out of curiosity, can you swap slides / frames between OR and regular Shadow 2?

If I understand your question correctly, then yes, the 92 has notably fatter grip than the SP01 and I don't know anyone who really wished the grip on the 92 to be bigger. I find it fairly comfortable and, at 183 cm tall, I have even looked for thinner grip options. As a reference, I shoot Shadow 2 and I use custom sized thick Lok grips to get me enough surface. The 92 grip is shorter but I've not found this to be a problem.

90 min later, after giving up on removing it manually by file, I had to whip out dreaded D-tool 20 min later, after careful trying in and out, everything is running as it is supposed to. Comparing to a standard disconnector, what I had there was massively thick. The thumb safety was indeed 2 minutes of very light and selective filing. I am glad the diagnoses were correct, as were the remedies.

I tried to search but fell short. I've a a hunch that our local CZ gurus will know the answers before I found it myself in 2 days. I've just assembled a brand new Shadow 2 after a detailed strip. I have a competition hammer / short reset disconnector / hammer strut that were fit by CZC custom (their parts) to another gun. I attempted to drop those parts in, and I also changed a trigger to an 85C. I think I put everything together correctly. The OT screw is removed from the trigger. In dry fire double action mode trigger moves hammer back and drops it seemingly correctly. If I rack the slide and cock the hammer, I can't drop it, neither manually nor by pulling the trigger. Subsequently, I have just put together my second Shadow 2. The difference from the first one is that I have a drop-in short reset disconnector. The second gun functions normally in dry fire, both DA and SA. However, the thumb safety doesn't work normally. The only position where I can move it up is hammer half cock. Fully cocked, no go. So, gun # 1 doesn't drop hammer in single action. Gun # 2 safety doesn't engage other than in half cock position. Oh joys of figuring things out myself. Help!!!! P.S. After monkeying around with both guns, it appears that #1 doesn't reset in single action, and # 2 needs safety to be fit. So, file on the inside surface of disconnector for the first gun's problem, and on that little nub on safety or sear for the second?

Thanks for the link, their site wasn't working on the cell phone for some reason. Specs say "weight empty", hopefully it means "with empty mag", as the photo next to specs implies.

So we think it'll make the weight for CO with extended mag and optic? Unlike Shadow 2, I don't see much room to shave off any weight with aftermarket work, and I can't find specs with weight on SF.

Latest rumor I heard that 43 and 48 are only different in slide / barrel length.

Does CGW poly rod extend all the way to a hole in the slide? CZC polymer rod is slightly shorter, doesn't see to have function issues but I wonder if it can induce a malfunction under some circumstances. I am waiting on custom fat lightweight lok grips to see where this leaves me. Also got that slide stop pin so I am nearly certain I'll make the weight. Question is if margins are big enough to account for possible scale to scale variability.

Well, until they hit 2000 units, whatever the price is, they aren't of any practical interest to competitive shooters, are they?

I checked my notes and apparently I can't keep things straight. It is the opposite. Henning extension with mecgar tube and Grams follower is lighter than the same setup with a CZC extension by 0.1 oz, 3.8 oz vs 3.9. Sorry for confusion.

I figured that was the case. I ordered a couple of those pins on Friday, CZ USA had them in stock. Funny, they weren't in stock the day before. When weighing my own gun with a mecgar mag + CZC extension vs mecgar mag plus Henning extension, the former was lighter.

I didn't know those existed, thanks to both of you. I am not a big fan of a palm swell design, I like a uniform thickness. But I wonder if I could talk them into making a light weight version of what I have now.

I've hard time following all CO new rules. I presume it is CO legal because small parts change is OK now? To the point of the original discussion, it seems to me that the CZC extension is slightly lighter than Henning. I don't have a TTI one. My Shadow 2 rod + mag, with a DPP directly milled into it by Primary, with several slide lightening cuts, plastic guide rod, and fat Lok grips (0.6 oz) is currently at 45.3 oz. I am a bit reluctant to remove the shroud. Next step likely the scales, I need volume to my grips, flat Lok or Henning grips not enough. May have to have dust cover milled out.
