I have (had? - stay with me) a Para-Ordnance P13.45 (Commander-length double stack) that I used to use in local competitions. For a combination of reasons I gave in and started using a P14.45 for competition. I recently discovered through this forum that Para used to offer the same pistol in .40 S&W, as the P15.40. I had never seen one, and had never even known they existed.

And then I discovered to my amazement that Brownells stocks the P15.40 slide and barrel. Since I didn't own any 1911 in .40 S&W, I bought the parts and I have now converted (subject to test firing to confirm that it functions) the pistol to a P15.40.

My problem is that I try to keep an accurate record of rounds fired through each pistol and of any malfunctions. It's perhaps a bit on the obsessive-compulsive side, but it helps me feel that I have some sense of where each pistol stands, especially with regard to recoil spring replacement. I use Excel, with a separate worksheet for each pistol. The P13.45 is in there, with several hundred rounds through it. The problem is -- now that I have converted it, do I just put an entry that it has been converted and keep the count running, or do I stop that page and open up a new worksheet for the new P15.40 configuration?

What would you do?

I would have one for the frame(possible just rename the one you have now),one for the original slide(unless you don't plan on switching back and forth), and one for the current setup.
Just my $.02

I agree, I think I would track each configuration and cumulative on the frame. I am no excel wizard but you could probably track the cumulative with a formula of some sort.

I also use Excel for my 1911's....separate worksheets for each.

1. I would keep the same worksheet.

2. Make an entry for the Conversion Date designating the P15.40 configuration.

3. In the column for your "round count".....start a "new round count" for your P15.40.

4. I would also use a different font color for each of the P15.40 entry columns. Another option would be to "shade" all the P15.40 cells, (columns)...that might be overkill, however.


In my view, even though the .40 conversion has taken place, it would still be the same pistol. Having everything on the same worksheet IMO, would make things easier to track and also provide a more concise history.

That's how I would do it.

I'll echo the previous statements. I'd separately track the rounds through the .40S&W hardware, and keep a cumulative tally of all rounds through the frame.

It's like installing a new engine in an old car. Yeah, you clock the miles on the new block but you also track the car's overall mileage too.

I would track each slide seperatly and include the frame ser# to keep track of the frame use.

I'd shoot it til it got dirty and then buy a new one made in the US of A.

And then clean it if it like... stopped or something...or dunk it in simple green and blow it off with an air hose and then oil it?... I never get this right... Ok... shoot it till it stops and then oil it and shoot it some more....no that's not right... ummm... how's this ... shoot it till it gets dirty, clean it, shoot it till it gets too dirty, clean it... repeat as needed...noooo then how will he know when to change springs cat boy... pshaw... OK... now I got it... shoot it till it gets dirty... but only shoot ammo out of a 1,000 round box... try to shoot 1,000 rounds without cleaning and then clean and repeat as needed... then he would know when to change the springs... but what about the 40 vs the 45 round count cat wonder....OHHHhhhhhh I give up... never could count rounds through a gun anyway as I fall into the shoot it till it gets dirty or the end of the session crowd... or clean it before I carry it...my wife cleans it before she shoots it... that way after it is cleaned it is test fired and she can be sure it works.... SOMEBODY TELL ME THE ANSWER... I AM SO CONFUSTICATED...

On a more serious note... I have never counted rounds through a gun except on a most rough basis... how many cases I have run through it approximately... I always sort of admired those who have the discipline to keep a log...seriously.... I'm not kidding...

I'm lazy, so I would just set-aside the 40 small pistol primer trays or flap of the new 40 if you don't reload 40's, and that would be "my count" for the 40 conversion.

Perhaps, "note" in the book when you have an issue with the 40. Update the excel form from the "tray count" and dispose of trays every once in a while.

I agree with the separate round count for each caliber configuration and another for the frame.
