Just to add some points for your consideration in relation to your legoing exercise:
1. Weight, it is not just because it is heavier, but with your Springfield being a polymer frame, polymer frames are particularly sensitive to stoppages caused from the frame being flexed under recoil from the weight. Sure the older mounts were designed with this in mind, but it is still a consideration, especially considering the extra weight. I can't say being so front heavy would help you balance / ergonomics wise either
.
2. Barrel clearance, enough said but you REALLY don't want to cut it close there
not to mention the amount of area that is exposed for Carbon to build up on the lens being right at the point of exit at the barrel.
3. IMHO you are at the practical limit using the MN11 bulb as far as effective light needed for a pistol. I'd suggest if you really feel you need more light or throw than 225 lumens, buy a M6, and use it as a handheld in conjunction with the pistol. If you're planning a night time trip to the metallic silhouette range perhaps you may need more throw
4. Holster fit may not be a concern, but just in case good luck on that one
5. Tim I give you an A+ for effort
. I presume you don't intend to be using this setup as a duty or service pistol. If that is the case however please ignore my other logical considerations and allow me to send you to the time out corner to give you time to think things through

Hope i've been able to help, and my above post is meant to be light hearted :santa:
Legoing is certainly fun isn't it
