Looks good, and that is the stamped steel version trigger guard.
If there is a significant amount of pressure needed to close the guard that will be normal and what you want. If it was easy to close it would indicate that either the stock (the wood stock) is thin between the top and the surface where the trigger rides or rhat the guard lugs/receiver channel is worn. The steel parts are well hardened so the more likely culprit is the stock.
If you have to push hard to close the guard, say for the last 30 degrees or so, then just look to the small portion that clips into the notch on the receiver. Usually it's pretty difficult to bend only that little tab so most folks just bend the whole guard, sometimes with a rubber or hardwood mallet, as loadedround described.
It's sort of a "feel" kind of thing - doesn't take much to get the clip to stay closed and doesn't take much the wrong way to have it pop open unexpectedly. Most of mine need a pry with a large screwdriver or the like to open and keep my hands from taking a thump.
Whatever, it's pretty hard to do any permanent damage to those pieces as long as you keep files or dremels out of it.
EDIT: You know, I just took a longer look at your photo. Your trigger is set a little low in the stock, I think. This may not be a problem, but if your trigger guard is easy to close it could be that the stock was cut too narrow or the trigger inletting was made a little too deep. It looks like a new aftermarket stock - did it come from the ones that CMP is selling?
