The 1911 still has a strong following in those crowds. The design can take a 1000 round shooting session and not result in stoppages common to those designs with the large block in the chamber as it expands and hangs on the hood in the front of the slide area. (Per a SEAL once romantically involved with a family member)
OK....... and how many times has this been useful?
1st, the handgun is not your primary weapon, thats what MP5's and M16's are for.
2nd, how much ammo is this guy gonna carry? For his backup, last ditch weapon? 1000 rounds of .45 aint light.
3rd, the SEALS use the H&K SOCOM .45 anyway.
Sounds like a posterior smoke blowing to me.
