I doubt Tanfoglio will tell you anything since it's an EAA serial number. The manufacture date would likely be no more than a few months before the import date.

You can email me the pictures and I'll post them: kneelingatlas@gmail.com If you want to know the date of import, sent the serial number to sharon@eaacorp.com. If the serial starts with AE it's pretty 2005, I have three with serial numbers 15xxx, 20xxx and 22xxx all imported in 1992.

That's a 10mm Hunter with a .40 barrel

I haven't noticed any difference in accuracy, but I can definitely feel the extra weight.

I used the ProChrono, it's cheap and easy. It sounds like you have a decent load to start with which is probably in your book. If you hold the bullet, powder and primer constant, the possibilities are not too overwhelming

Welcome to the fraternity of handloaders, there are enough variables to make your head spin! You mentioned a few variables: tight groups, recoil feel and power factor; chances are good you will never find a load which optimizes all three. You might find the softest shooting load produces terrible groups or that the most accurate load is way over the minimum power factor for the game you want to play. Other factors like reliable feeding, smoke, clean burning, cost, etc. will also likely influence your "go to load". To answer your question, you will never know you've found the holy grail of loads with your gun; the best you can hope for is a load (or a handful of loads) you're happy with. The best thing about this forum is all the knowledge shared so I suggest you first find a popular powder you can get, then pick a bullet, find a starting point and go. Once you have a load which works reasonably well, you can start experimenting. Do you have any components right now?

I suppose you could, but fast powders are designed to burn fast and not produce a lot of gas. The more gas, the better the comp works. I would bet getting to major PF with N320 and 115 would probably create excessive pressure and risk blowing up you gun.Stay with known powder and bullet combinations! 320 would probably show excessively flat primers before reaching major, but I've never done it so I could be wrong...Regardless, the comp would do little if anything to mitigate muzzle flip, which really is the point.

From my testing of the Thunder Comp II, the side holes take away from the efficiency of the comp in countering muzzle rise.

Very interesting...

When commenting on a thread comparing a 9mm 1911 to a CZ, I became interested in comparing different attributes of the two platforms (namely slide weight, stroke, barrel length and recoil system length) and how they effect performance. I have some qualitative ideas, but before I spend a lot of time gathering data, I figured I would ask if anyone already has any of this info. For the purposes of comparison I think it's most useful to refer to everything by it's native barrel length, for example a GI 1911 slide is a 5" slide even though the slide measures longer than 5". Most builds I've seen with slides shorter/longer than 5" seem to still utilize a 5" recoil system so it would seem, at least for the 19/2011 platform, a 5" recoil system seems like the sweet spot.

Rich brings up good points, but if you're going custom, why scrimp on the length

Lester, I'd be interested in quantifying some of this stuff. The 1911 is a large frame, so it has a longer stroke than the small frame CZs but I'm not sure how the stroke of a large frame Tanfo compares to a 1911. I think the 5" recoil system vs the 4.5" recoil system in the CZs is a big factor too. It has always interested me that the 40 TS (5.1" barrel) has a reduced recoil system. A lot of 6" 2011 builds also use a recoil system shorter than 6"...

You know I just read that burn rate and its way different than their last one and at least with the powders we're talking about it's not consistent with my data. With 115s it takes me 7.2gr to make major w/ Autocomp and 8.6gr of HS6.

That's not true. The pro has a straight barrel like a Match.

http://www.hodgdon.com Check out the burn rate chart, Autocomp and Silhouette are the fastest of the popular powders, HS6 and 3N37 are in the middle, with 3N38 and N105 being the slowest powders suitable for major in a 9mm. Your barrel sounds fast so you might make major with N105 unless you start drilling holes in it Posting a picture of your comp is probably the best place to start. You dont want to start drilling holes when you could just switch comps and be much happier. But like I said earlier, if you take note of where the dot is when you break the second shot those groups will tighten up right away. There are plenty of SS shooters ripping pairs of alphas in a hurry using 45s with no comps, so its not the gun

I like a light spring (10-12#) and the Czechmate hammer (I've tried them all), it drops in for the most part (maybe a little safety fitting).

It sounds like you have an issue with technique you're hoping the equipment can fix. You can only shoot the second shot as fast as you see the dot on target again. A flatter gun can help, have you tried 115s? Here are my thoughts: you're using a full sized gun with a small powder charge of a fast powder and a heavy bullet (obviously all relative terms) so you're on the soft side of the soft/flippy vs violent/flat side of the spectrum. You can certainly move the gun you have down the spectrum with lighter bullets and slower powder to see how you like it before you commit to a new build.

Limited is the gun for Limited. The Pro is a Production gun. If you can't find one in 40 there's a limited Pro 40 upper for sale in the classifieds you could swap on.

I used 115s because gas is the name of the game in Open and more powder makes more gas right? I find it interesting how many 38 shooters dont use the extra capacity, if your load is ~9gr of say 3n38 under a 124 and my 9 load is ~9gr of the same powder under a lighter bullet, where's the advantage?

Me too. I literally have no idea how many times I have loaded some of it. There isn't as much voodoo involved in 9MAJOR as people would have you believe. Be careful and pay close attention to what goes in, and what comes out of your press, and you will be fine.Paying 13 cents for star line 9mm brass would be absolutely insane! Yes! I can't stand hearing people talk about how dangerous 9 Major is, with 115gr bullets and SP2 I can literally fill the case right to the brim, seat a bullet and not get near as flat a primer as I do with my shorty 38.

Welcome Rick, where in the state? I'm in San Diego.

Here's a picture of a Tanfoglio Limited superimposed on a 1911: You can see the big difference is the position of the beaver tail. Because the slide in frame design uses a shorter slide, you can grip the gun higher, getting the bore axis closer to your wrist. Short dust cover CZ vs 9mm 1911? I've never shot a 9mm 1911, but I would guess it shoots softer due purely to extra half inch of length and recoil system.

Awesome!

I think this is a case of conventional wisdom which is outdated. The modern .22s I've checked limit the firing pin travel to a point where it can't touch the breech.

There must be some attraction to slide lock I've never seen, I've never liked the inconsistent recoil impulse on the last shot and I think the dry 11th shot is great measure of your trigger control.
