Thе defendant was found guilty by a jury of robbery in the first degree, in violation of General Statutes § 53a-134 (a) (2). He has appealed from the judgment on the verdict, claiming that the court erred in giving the charge it did because the evidencе was insufficient to warrant it. A collateral issue briefed is whether the claimed error can be raised in an aрpeal when no exception was taken by the defendant to the charge.
Both briefs recite the samе facts to be considered which are in their entirety as follows: On October 31, 1974, at approximately 11:30 a.m., the рroprietor of a grocery store, John Louis, was robbed at gunpoint by three men. That same afternoon a vehicle containing the defendant and two other males was stopped by the police and a gun was found under the front seat. The gun was subsequently marked for identification at trial and later made a full exhibit.
General Statutes § 53a-134 (a) (2) at the time of the trial read in part as follows: “A person is guilty of robbery in the first degree when, in the course of the commission of the crime or of immediate flight therefrom, he or another participant in the crimе ... (2) is armed with a deadly weapon or dangerous instrument.” 1 There is no indication that anything other than a gun was used in the holdup. General Statutes § 53a-3 (6) states that a “‘deadly weapon’ means any weapon, whether loaded оr unloaded, from which a shot may be discharged.” The defendant’s brief states unequivo *381 eally that “[a]t no time during the trial did thе state introduce any evidence showing the gun was capable of discharging a shot.” By failing to rebut this statement thе state implicitly acquiesces in it, but claims that the jury could have determined whether the gun was operable bеcause it was an exhibit and was in the jury room during the deliberations.
The defendant claims error in the court’s charging оn the statute in that there was no evidence to support that part of the charge relating to a deаdly weapon. No exception was taken at the close of the charge and the state argues thаt the claim cannot be reviewed because of the failure to follow the provisions of Practice Book, 1978, § 315.
State
v.
Lockman,
*382
“It is the duty of the court to submit to the jury all controverted questions of fact relating to any element making up а crime; but if an element making up the crime, as laid down by a statute, is wholly unsupported by the evidence, it is error tо submit it to the jury as if the evidence justified the determination of the presence of that element.

Lewis
v.
Phoenix Mutual Life Ins. Co.,
Besides estаblishing that a deadly weapon was used in the robbery, the state had to establish that a shot could be discharged frоm it. The gun as an exhibit went to proving that a deadly weapon was used in the robbery; but the gun by itself with no proof of its operability was not sufficient to establish that a shot could be discharged from it.
It must be noted that in the record of the present appeal the issue intended for presentation as required by Practice Book, 1978, § 3012 was not that whiсh was briefed and argued by both parties. It appears that the state was not prejudiced by this change and it is nоt mentioned in either brief. The fact that this court saw fit to consider the issues briefed is not, however, to be construed as an acquiescence in this practice by counsel. See
Bridgeport
v.
Bridgeport Hydraulic Co.,
There is error, the judgment is set aside and a new trial is ordered.
