I purposfully went and bought the removable mag version of the model 10. No trouble with any of the possible problems you mentioned. I like the way it allows me to reload as compared to the usual method. But the mags cost $60 each so not cheap if you lose one , but I have had mine for almost two years and have the original mag. I think detachable mag is more of a tactical advantage than anything else. But as long as the deer dont shoot back a standard internal might be fine for you.
