Not a bit. The men in the SEAL teams could (and can) use every edge they can obtain. I carried the Glock 20 for at least ten hours a day in a Sam Browne belt in a uniform a minimum of 5 days a week.
These men are in their early 20's at their peak of strength and training. I was 50 years old at the time. (I think they can handle it).
First of all, not all SEALS are in their early 20s. Some of them start into the program at that age, but many of them are quite a bit older.
We have to keep in mind that handguns are not their primary weapon as might be the case for an LEO -- and that seems to be your focus. An LEOs weapon needs are different than a SEAL's. For that matter, even SWAT teams seldom go into potential confrontations with handguns only.
The two SEALS participating on the AR15 forum made the point that every extra bit of weight mattered, and they welcomed a lighter weapon -- as they might be carrying 70+ lbs of gear at different times.
- A loaded Glock 20 weighs 39.71 ounces (about 2.5 pounds),
- a loaded P226 Mk25 (the version used by SEALs) weighs 34.4 ounces (2.2 ounces),
- a loaded P228(M11A1) is 34 ounces (2.2 ounces)
- a loaded Glock 19 weighs 30 ounces, or 1 lb. 14 ounces.
If you're talking logistics, that weight difference and the weight of extra ammo also carried might be significant. Scrounging for ammo in the field, if you run low, is likely to be almost impossible for a 10mm weapon.
SEALS and other Special Ops troops sometimes have to carry concealed on missions (when not in combat gear) and the two SEALS mentioned above said they chose the smaller SIG P228 (M11A1) over the P22 for that usage. Size, not weight, was the concern. Both thought the Glock 19 would effective in that role.
